📺 Watch & Subscribe on YouTube
"Our microhabitat is completely different from the microhabitat that we had 150, even 200 years ago," says Lilliana Lettieri, who joins the Quantum Biology Collective podcast to reveal how our modern light environment is fundamentally altering our biology. Together with Peter Veto, Lettieri is pioneering a revolutionary technology that could transform our relationship with screens: monitors that emit actual sunlight. This groundbreaking innovation channels daylight through fiber optic cables, potentially eliminating the need for blue light filters and other mitigation strategies.
In this illuminating discussion, Lettieri and Veto explain how our current digital displays bombard our cells with unnatural light cues, contributing to a host of health issues from eye strain to metabolic disruptions. They share their personal health journeys that led them to this work, and how their diverse backgrounds in biology, psychophysics, and consumer electronics converged to create this sunlight-powered screen technology.
Tune in to today's episode to learn why your office lighting might be secretly sabotaging your health, how fiber optics could bring healing sunlight into windowless spaces, and why the future of screens might be brighter—literally—than we ever imagined.
5 Key Takeaways
1. Sign up for Pixun's newsletter and follow them on social media to support the development of sunlight-powered monitors. This helps demonstrate interest to potential investors.
2. Consider how sunlight-powered screens could benefit environments like elder care facilities, hospitals, and schools without adequate natural light exposure.
3. While waiting for sunlight screens to become available, continue mitigating the effects of current screens by using blue light filters and taking regular breaks.
4. Recognize that digital eye strain can come from multiple factors beyond just blue light, including flicker and narrow light spectrums. A holistic approach to eye health is important.
5. Stay informed about emerging technologies like Pixun that aim to make our digital interactions healthier. Being an early adopter and advocate can help shape a better future.
Memorable Quotes
"Our microhabitat is completely different from what we had 150 or 200 years ago. Within that, we're bombarding our eyes with a very specific cue that our cells and bodies are feeling, even if we don't consciously see it." - Lilliana Lettieri
"We have so many products to mitigate the effects of screens, which shows there's a problem. None of them truly work, because we keep having to use them. Digital eye strain can come from many causal pathways - spectrum issues, flicker issues - and it's hard to figure out which one affects you." - Peter Veto
"Screens are the only lighting application where the intended use is to look directly into the light source for several hours every day. It's a concentrated and impactful application, which is why we shouldn't focus solely on energy efficiency." - Peter Veto

Our microhabitat is completely different from the
Lilliana Lettieri:microhabitat that we had 150, even 200 years ago.
Lilliana Lettieri:It's completely different. And within that
Lilliana Lettieri:microhabitat that has a very different light
Lilliana Lettieri:structure, let's say, you know, if you're to see
Lilliana Lettieri:what's around there, the wavelengths and the
Lilliana Lettieri:intensity of the light and all of that, it's
Lilliana Lettieri:completely different. And then within that, we're
Lilliana Lettieri:also additionally bombarding our eyes with a
Lilliana Lettieri:very, very specific cue that even though we don't
Lilliana Lettieri:see it in our eyes because it's not necessarily
Lilliana Lettieri:in the visible wavelength, our cells are feeling
Lilliana Lettieri:it, our bodies are feeling it.
Meredith Oke:Welcome to the QVC podcast, where we explore new
Meredith Oke:paradigms in health and science that have a
Meredith Oke:meaningful impact on our day to day lives. I'm
Meredith Oke:your host, Meredith Oak, a curious coach and mom.
Meredith Oke:I started a journey to overcome chronic fatigue
Meredith Oke:and found myself in a whole new quantum universe.
Meredith Oke:I believe new research shouldn't stay locked away
Meredith Oke:in an ivory tower. And that wisdom can be found
Meredith Oke:in many places and understood by all of us. To
Meredith Oke:keep in touch with this podcast, the QVC free
Meredith Oke:community, our episode guide, and all the show
Meredith Oke:notes, please visit qbcpod.com qbcpod.com let's
Meredith Oke:get together to create the future we all want to
Meredith Oke:live in. Okay, you guys, the guests on my show
Meredith Oke:today are making something that is so super cool.
Meredith Oke:I don't, I don't even know what to say. It's like
Meredith Oke:the craziest thing. And I have to say, Peter Vito
Meredith Oke:and Liliana Lettiari, who are my guests today,
Meredith Oke:have been working on this for a couple of years.
Meredith Oke:They've been on my radar and, and you know, they,
Meredith Oke:we even did a deep dive with them in QVC Pro in
Meredith Oke:deep into their science. And I'm kind of
Meredith Oke:embarrassed to say. I was sort of paid attention
Meredith Oke:to what they were talking about, but not really
Meredith Oke:until I decided to have them on my podcast and I
Meredith Oke:started really looking at what they were making.
Meredith Oke:I was like, oh, okay, yeah, it's a, it's a new
Meredith Oke:kind of screen. All right, that sounds good.
Meredith Oke:Like, yeah, for sure, for sure. And then I
Meredith Oke:started to research what exactly these guys are
Meredith Oke:doing, and it's crazy.
Lilliana Lettieri:I'm like, what?
Meredith Oke:How are we not all so super excited about this?
Meredith Oke:Okay, so when I explain it to you, you're going
Meredith Oke:to get really excited. It's not available yet.
Meredith Oke:They're still, you know, building out the
Meredith Oke:prototype and working on getting their company
Meredith Oke:going, but what they've done is they've created a
Meredith Oke:monitor. So a screen that can be used for,
Meredith Oke:attached to any computer. You could use it as a
Meredith Oke:television. You know, it's a monitor that is lit.
Meredith Oke:The light coming out of it is sunlight. Yes,
Meredith Oke:Correct. The monitor emits sunlight. The sunlight
Meredith Oke:is collected outside, travels through a fiber
Meredith Oke:optic cable and, and comes out of the screen.
Meredith Oke:Like, what? So now it's not. We're not trying to
Meredith Oke:mitigate. We don't have to do all these hacks to
Meredith Oke:mitigate the toxic light coming out of the
Meredith Oke:screen. The light coming out of the screen could
Meredith Oke:actually just be sunlight. Yes, yes, yes. We
Meredith Oke:still want to go outside and do all of those
Meredith Oke:things, but what if the time that we did have to
Meredith Oke:spend on a screen was good for us? Like, it's
Meredith Oke:crazy and this thing actually works. It's real.
Meredith Oke:So I, I'm going to let them get into it and
Meredith Oke:explain the story of how this all happened.
Meredith Oke:Liliana and Peter both have PhDs. Peter has a PhD
Meredith Oke:in psychophysics. And Liana, Liliana is more
Meredith Oke:cross disciplinary. She studied a lot of
Meredith Oke:different kinds of sciences. So this is one of
Meredith Oke:those situations where it's like, as with
Meredith Oke:anything that is working in the world today, it's
Meredith Oke:interdisciplinary, it's abolishing silos. It's
Meredith Oke:people with different backgrounds coming together
Meredith Oke:and going, what if we did this? What if we tried
Meredith Oke:this? Peter's really focused on the science and
Meredith Oke:Liliana is building out the business and I
Meredith Oke:couldn't be more excited to support them in that
Meredith Oke:endeavor. So enjoy this conversation. In the
Meredith Oke:meantime, since a sunlit screen is currently not
Meredith Oke:in any of our living rooms or on our desks or on
Meredith Oke:our tables or on our screened in porches where I
Meredith Oke:currently am, we still should be mindful of how
Meredith Oke:we use them and, you know, download all the
Meredith Oke:filters for during the day. That's what I do. If
Meredith Oke:people are like, why are you wearing blue clips?
Meredith Oke:You don't wear blue blockers during the day. I
Meredith Oke:use, I use the iris filter and I during the day
Meredith Oke:and then in the evening if I need to be on a
Meredith Oke:screen or I'd like to watch a movie or a TV show
Meredith Oke:with my family, I put on the blue blockers, which
Meredith Oke:I get from boncharge.com our partner on this
Meredith Oke:podcast. So if you are using a screen and you
Meredith Oke:don't have blue blockers, you should really go
Meredith Oke:get some. The code is QBC at checkout for a
Meredith Oke:discount. And now back to the future of screens
Meredith Oke:with Liliana and Peter. Peter Vito. Liliana
Meredith Oke:Latieri. Welcome to the QVC podcast. I'm really
Meredith Oke:excited to have you both here. For people who
Meredith Oke:don't know, I mean, I just will have said it in
Meredith Oke:the intro, but you're working on some really
Meredith Oke:exciting technology that literally brings
Meredith Oke:sunlight into our computer monitors. So we're
Meredith Oke:going to get into it. But I first want to ask how
Meredith Oke:you both arrived at this project. It's in some
Meredith Oke:ways seems so intuitively correct and in other
Meredith Oke:ways is just completely cutting edge and mind
Meredith Oke:blowing that you're doing this. Love to hear how
Meredith Oke:you ended up making a sunlight fueled screen.
Lilliana Lettieri:Yeah. So I'll give you a little bit of my
Lilliana Lettieri:background because I think in context, maybe it
Lilliana Lettieri:makes a little bit more sense about how I met up
Lilliana Lettieri:with Peter and why it all made sense to me
Lilliana Lettieri:immediately. So I was trained in biology. I
Lilliana Lettieri:worked looking at organisms and how they signal
Lilliana Lettieri:and use color and light to interact and, and to
Lilliana Lettieri:survive in their specific environments. So what I
Lilliana Lettieri:learned was all about vision and how colors and
Lilliana Lettieri:wavelengths move through the environment in very
Lilliana Lettieri:specific ways and in specific channels. And you
Lilliana Lettieri:know, what we tend to think of as color is based
Lilliana Lettieri:on our categorical way of using light to
Lilliana Lettieri:interpret our environment with our specific
Lilliana Lettieri:cones. Right. But bees or mantis shrimp or birds,
Lilliana Lettieri:they all have very different ways of interpreting
Lilliana Lettieri:their environment. So that's sort of always been
Lilliana Lettieri:an understanding. And then I eventually moved
Lilliana Lettieri:into the business world, into signaling in a very
Lilliana Lettieri:different way in home electronics, consumer
Lilliana Lettieri:electronics, and learned about Bluetooth and WI
Lilliana Lettieri:fi and how data is brought in to your home and
Lilliana Lettieri:signaled throughout the environment. And so
Lilliana Lettieri:that's sort of where I came to this understanding
Lilliana Lettieri:when I reached sort of my, my health awakening,
Lilliana Lettieri:if you will. That, that then brought me to, to
Lilliana Lettieri:meet Peter.
Meredith Oke:That is so fascinating. And of course, what
Meredith Oke:strikes me first is, and I find this with
Meredith Oke:everybody who has deep insights in this field is
Meredith Oke:that there's almost always overlapping fields
Meredith Oke:that aren't necessarily ever supposed to, under
Meredith Oke:normal circumstances, talk to each other. So in
Meredith Oke:your case, you were looking at biology and
Meredith Oke:specifically how insects see. And then you moved
Meredith Oke:into a job that required you to understand how we
Meredith Oke:receive technology into our lives in our homes.
Lilliana Lettieri:Right. So it was actually fishes, believe it or
Lilliana Lettieri:not. So I was actually setting up things to
Lilliana Lettieri:measure light and communication with color
Lilliana Lettieri:underwater in big contrast and building rigs, you
Lilliana Lettieri:know, that would hold a camera and taking
Lilliana Lettieri:measurements with little underwater contraptions
Lilliana Lettieri:and trying to figure out how organisms
Lilliana Lettieri:communicate to each other in the ocean. So then
Lilliana Lettieri:moving into technology, you know, it's a whole
Lilliana Lettieri:new world. But to me, it all Interconnects very
Lilliana Lettieri:much. I mean, I was trained as an
Lilliana Lettieri:interdisciplinary scientist. I took classes with
Lilliana Lettieri:chemists and engineers, and, you know, the whole
Lilliana Lettieri:idea was to sort of like, bring these fields
Lilliana Lettieri:together, learn how to talk to one another in a
Lilliana Lettieri:way that's not so, you know, filled with jargon,
Lilliana Lettieri:that you're like, I don't know what you're
Lilliana Lettieri:talking about. You know, that I can see that
Lilliana Lettieri:you're very smart, but I don't understand what
Lilliana Lettieri:you're, what you're speaking about. So we learned
Lilliana Lettieri:to talk to one another, you know, in a common
Lilliana Lettieri:language. And I think that that has served me,
Lilliana Lettieri:you know, down the road to be able to talk to
Lilliana Lettieri:people from different fields and understand that
Lilliana Lettieri:we're, We're. We're. We're tackling the same
Lilliana Lettieri:problem, but from very different, you know,
Lilliana Lettieri:expertise. So.
Meredith Oke:Oh, I love that. And, you know, I really think
Meredith Oke:that, yeah, this siloing of science and research
Meredith Oke:and even industries, you know, you have like, the
Meredith Oke:FTC regulating ems, and they don't, like, what
Meredith Oke:did the FTC know about biology? Like, they went
Meredith Oke:to decide, make business decisions. Right. Like,
Meredith Oke:so this, this siloing has been hugely
Meredith Oke:detrimental, I think, to civilization. So I love
Meredith Oke:that you're weaving things together and doing it
Meredith Oke:in a way where you can talk about it publicly.
Meredith Oke:My, My soapbox right now is that science needs
Meredith Oke:storytellers. I, you know, everyone I talk to,
Meredith Oke:it's like, I know we're just at the beginning of.
Meredith Oke:The beginning of understanding things, but
Meredith Oke:there's so much science there. Like, there's so
Meredith Oke:much. And I think a lot of people, myself
Meredith Oke:included, have kind of labored under the belief
Meredith Oke:that once there's enough science to prove
Meredith Oke:something, we'll just all magically know, right?
Lilliana Lettieri:We'll just all get it, shift to the new right
Lilliana Lettieri:thing.
Meredith Oke:And I'm like, oh, no, that's not how it works.
Meredith Oke:Okay, so, Peter, tell us your way into this world.
Peter Veto:Yeah, to connect to all of this, beyond the
Peter Veto:interdisciplinary background, of course, to
Peter Veto:pixel, and also to what we do, which is similar
Peter Veto:in that sense to that of Liliana's. The other
Peter Veto:common thread, I believe, is the personal
Peter Veto:involvement or having had the experience of
Peter Veto:health issues which relate to light and how
Peter Veto:increasing exposure to daylight can help with
Peter Veto:that and otherwise. I was also a researcher
Peter Veto:first, so before 2020, I was a researcher in
Peter Veto:psychophysics, studying human vision and
Peter Veto:perception, starting with electrophyll.
Meredith Oke:Okay, sorry, hang on. What is psychophysics? Tell
Meredith Oke:us more about that. That sounds cool.
Peter Veto:Psychophysics is basically measuring something in
Peter Veto:physical reality and using that as a stimulus and
Peter Veto:then measuring on the other end of the
Peter Veto:interaction something in the psychological realms
Peter Veto:to how animals or humans in my case react to
Peter Veto:that. Basically my main topics were around
Peter Veto:vision, so how we see things. And firstly
Peter Veto:starting with electrophysiology, so EEG and tms,
Peter Veto:which is measuring electric waves from outside of
Peter Veto:the skull, so electric activity of the brain. And
Peter Veto:then TMS is using electromagnetic policies to
Peter Veto:induce some activity in the brain. But then I
Peter Veto:moved on to psychophysics, which is kind of
Peter Veto:leaving this middle ground of the messy
Peter Veto:neuroscience part out and measures on what is
Peter Veto:more tangible. And so that came in my career, I
Peter Veto:think more just accidentally. But looking back,
Peter Veto:I'm very, very grateful for that because it
Peter Veto:brought me much closer to whatever is pragmatic.
Peter Veto:So measuring really reality and not just trying
Peter Veto:to figure out through some modeling what's going
Peter Veto:on inside. The biggest issue there being with all
Peter Veto:the neuroscience stuff, is that no one really
Peter Veto:understands what the brain does. So that's how I
Peter Veto:got to vision and action as well. So I was using
Peter Veto:their eye tracking, pupilometry, motion capture,
Peter Veto:stuff like that.
Meredith Oke:Okay, so I heard some interesting things in your
Meredith Oke:answer as well, which is that a lot of brain
Meredith Oke:science is done based on modeling and you prefer
Meredith Oke:to work on actual observations, which I think is
Meredith Oke:also really in the wheelhouse that we're all
Meredith Oke:operating in, which is how does this science help
Meredith Oke:people right now? What choices can I make in my
Meredith Oke:life, in my day to day life that's going to help
Meredith Oke:me right now versus just funneling it into
Meredith Oke:research and research and research that never
Meredith Oke:quite bridges into real life. And it's
Meredith Oke:interesting, I was YouTube served me up a video
Meredith Oke:just yesterday of some neuroscience guy who was
Meredith Oke:like, well, psychology and philosophy are fine,
Meredith Oke:but it's really neuroscience because now we know
Meredith Oke:that this part of the brain does this, and this
Meredith Oke:part of the brain, I'm like, you don't know
Meredith Oke:anything. Shut up. You and your 28 million, 28
Meredith Oke:million views on YouTube. But I just, it, it's
Meredith Oke:interesting to me the certainty with which people
Meredith Oke:can convey things that they've studied that
Meredith Oke:aren't, you know, really necessarily the whole
Meredith Oke:story at all.
Peter Veto:Absolutely. And the other thing that connects to
Peter Veto:here with what you said, is that we know plenty
Peter Veto:enough to do better in lighting in this place. So
Peter Veto:looking for impact, I was thinking I could do
Peter Veto:some more research and write papers which will be
Peter Veto:read by a few more academics and that's it. But
Peter Veto:actually we know plenty enough to know how it can
Peter Veto:be done better. And of course, daylight being the
Peter Veto:optimal Light source, it just really seemed
Peter Veto:trivial, but also, again, from personal
Peter Veto:experience and other backgrounds to how Pixar
Peter Veto:came to be. But this is one of it that it's
Peter Veto:always cool to know more and to dig into
Peter Veto:mechanisms, but if we can see which light source
Peter Veto:works better for people, that's a very simple
Peter Veto:thing. I think we know plenty enough about that
Peter Veto:to know how we could do better.
Meredith Oke:Yeah, exactly. It's like, okay, oh, this is
Meredith Oke:clear. Like, let's take some. Make some practical
Meredith Oke:changes to the world. So tell me, tell me about
Meredith Oke:your personal health story that led you to this
Meredith Oke:and your epiphany about daylight.
Peter Veto:In my case, this started really in 2018. I was a
Peter Veto:postdoc at Cambridge and working mainly in a dark
Peter Veto:length. So for these vision experiments and
Peter Veto:humans, we of course need a controlled light
Peter Veto:environment. So it's all dark with electric
Peter Veto:lighting and mainly display. So that's where I
Peter Veto:spent most of my day. And when I was not there,
Peter Veto:my office setup was really not very ergonomic. So
Peter Veto:the only chance I had to play somewhere desktop
Peter Veto:monitor was right in a west facing window. So it
Peter Veto:was always sunny when I got to that point in my
Peter Veto:day to use it. And I had to block the window and
Peter Veto:block the sun completely. And so that's when I
Peter Veto:was starting to think that I could just get rid
Peter Veto:of the backside of the monitor and use the
Peter Veto:sunlight for that. And meanwhile, because of more
Peter Veto:work and other issues, I also had increasing
Peter Veto:symptoms of light sensitivity. And I was looking
Peter Veto:for answers for that, which my professional
Peter Veto:really couldn't give. Again, it's not
Peter Veto:interdisciplinary enough so that lighting
Peter Veto:research would be connected enough to basic
Peter Veto:vision science, which, the latter, of course, was
Peter Veto:my field at that, at that time, let alone to
Peter Veto:anything. And that has to do with light
Peter Veto:physiology. And so that's when I started to learn
Peter Veto:more about this and realize that this is about so
Peter Veto:much more than.
Meredith Oke:So the requirements of your job where you were in
Meredith Oke:darkness a lot during the day. Is that right? And
Meredith Oke:then in front of your computer in the. So you had
Meredith Oke:like dark mornings, computer lit afternoons. Is
Meredith Oke:that sort of. That was the setup of your life and
Meredith Oke:then started to take a toll?
Peter Veto:Yes, definitely. Yes. And when I could have had a
Peter Veto:sun office space, I had to block the sun to even
Peter Veto:be able to see the monitor.
Meredith Oke:Okay.
Peter Veto:So I was thinking if I could channel the sun into
Peter Veto:the display, that would help with both. Both
Peter Veto:problems.
Meredith Oke:Wow, I love how your brain works. So what were
Meredith Oke:some of the symptoms that you noticed when you
Meredith Oke:were living a life where it was you had Darkness
Meredith Oke:for the first half of the day and then computer
Meredith Oke:monitor light in the second half of the day. How
Meredith Oke:were you feeling physically, mentally, like what
Meredith Oke:was going on?
Peter Veto:I think I have always had some sensitivities and
Peter Veto:especially for light, light sources which are
Peter Veto:weird. And that really started with car
Peter Veto:headlights a little earlier when LED headlights
Peter Veto:started to become more popular and I realized
Peter Veto:that I no longer enjoy driving at night and it
Peter Veto:took some while to even figure out why. And
Peter Veto:obviously that means that my symptoms were not so
Peter Veto:severe. But then this got much worse when I spend
Peter Veto:more time indoors, more time in front of computer
Peter Veto:screens and that then connects to headaches, all
Peter Veto:sorts of other issues and just eye strain in
Peter Veto:general with various symptoms. Part of that can
Peter Veto:also be temporary myopia which I experienced
Peter Veto:periodically, which is interesting because in my
Peter Veto:adolescent years I was myopic and then I kind of
Peter Veto:successfully trained myself out of it because I
Peter Veto:was lucky enough to be sent to a more forward
Peter Veto:thinking ophthalmologist who didn't just
Peter Veto:prescribe sunglasses, but also gave exercises and
Peter Veto:good advice, which in my case were wow. But I
Peter Veto:guess I'm still myopic in the sense that the
Peter Veto:symptoms can come back. And so this place can
Peter Veto:induce temporary myopia in many people. And it's
Peter Veto:still a somewhat open question how much that
Peter Veto:translates to longer term myopia. It seems to do
Peter Veto:translate to some degree and in my case that that
Peter Veto:is also part of the symptoms that I can
Peter Veto:experience. So I guess there are these flashbacks
Peter Veto:of blurry vision even though normally I don't
Peter Veto:have it and I don't need glasses any longer even
Peter Veto:for driving.
Meredith Oke:Wow. So you were having headaches and eye strain
Meredith Oke:and your. My myopia was getting worse.
Peter Veto:Yes, that's right. And I, I never have had that.
Meredith Oke:And then when you changed and had a. Yeah, when
Meredith Oke:you changed your lighting environment to get more
Meredith Oke:daylight during the day, what happened?
Peter Veto:Yeah, so this got pretty much fixed through just
Peter Veto:more, more awareness of how to organize my day
Peter Veto:and how to be exposed to daylight increasingly
Peter Veto:starting from the morning because I'm. I was
Peter Veto:especially then more sunsens as well. So it
Peter Veto:really needs to start gently and with daylight.
Peter Veto:And that just helps and reduces all the
Peter Veto:sensitivity symptoms also to bright sources
Peter Veto:including headlights. And it doesn't go away. And
Peter Veto:who knows why that is the case really. I don't
Peter Veto:think we understand why some people are sensitive
Peter Veto:to LEDs and others not. There are many aspects to
Peter Veto:this, but at least you can reduce the symptoms by
Peter Veto:just being more aligned to nature.
Meredith Oke:Yes, and that's true A lot of the time when I
Meredith Oke:talk to people about this, they're like, oh, I
Meredith Oke:can't go outside. Like, it's too bright. My eyes
Meredith Oke:are, you know, and that's actually a symptom of
Meredith Oke:not being outside enough. So what you're saying
Meredith Oke:is you went out, you started early in the morning
Meredith Oke:before it's like super, super bright and, and
Meredith Oke:gradually adjusted. Seems like a good way to do
Meredith Oke:it.
Peter Veto:Exactly. This is huge. And so many people say
Peter Veto:that, oh, the sun is stronger now than it used to
Peter Veto:be. And as children they were, whatever, playing
Peter Veto:outdoor all day long and it didn't burn them. And
Peter Veto:it doesn't even occur to them that it's not so
Peter Veto:much probably the sun that changed, but they
Peter Veto:have, right?
Meredith Oke:Yeah. Their environment, their indoor environment
Meredith Oke:has changed, which has made us more sensitive to
Meredith Oke:our outdoor environment. Liliana, what's your
Meredith Oke:story of coming to understand how important light
Meredith Oke:is and natural light is in terms of overall
Meredith Oke:health?
Lilliana Lettieri:Yeah, so I would say after about a decade in
Lilliana Lettieri:academic research, which was many times in labs
Lilliana Lettieri:and, you know, very controlled lighting
Lilliana Lettieri:environments and indoors largely, and then
Lilliana Lettieri:transitioning into the business world where I was
Lilliana Lettieri:often on calls with international teams before
Lilliana Lettieri:sunrise and then after sunset and just, you know,
Lilliana Lettieri:a lot of screen time, a lot of indoor office
Lilliana Lettieri:spaces and a lot of exposure to different
Lilliana Lettieri:communication varieties, I started to experience
Lilliana Lettieri:sort of weird metabolic related symptoms, you
Lilliana Lettieri:know, and, and I sort of first attributed it to,
Lilliana Lettieri:oh, it seems like it's maybe early menopause,
Lilliana Lettieri:early perimenopause and you know, hot flashes,
Lilliana Lettieri:night sweats, headaches, insomnia, dopamine
Lilliana Lettieri:dysregulation, just all kinds of weird things
Lilliana Lettieri:that, you know, if, if I talk to people, they're
Lilliana Lettieri:like, oh, you're just getting older, that's
Lilliana Lettieri:normal. And, and I, and I, you know, I, I sort of
Lilliana Lettieri:took that as the acceptance storyline at the
Lilliana Lettieri:time. And then it started to really feel like
Lilliana Lettieri:this isn't quite, I don't really feel like this
Lilliana Lettieri:is the root, this isn't really what's happening.
Lilliana Lettieri:So I started to really do some more research and
Lilliana Lettieri:when I started to learn more about this, you
Lilliana Lettieri:know, the circadian science and really started
Lilliana Lettieri:to, you know, recognize and make the connection
Lilliana Lettieri:between like, oh, my natural environment is very
Lilliana Lettieri:unnatural and so maybe I need to really realign.
Lilliana Lettieri:And so when I started to do that, these symptoms
Lilliana Lettieri:started to go away on their own. And, and you
Lilliana Lettieri:know, and then I was, then I, it was like the
Lilliana Lettieri:light bulb really went off and I was like, okay,
Lilliana Lettieri:I really need to learn a lot more about this and,
Lilliana Lettieri:and I really started to piece together that,
Lilliana Lettieri:well, two things that one of the things that I
Lilliana Lettieri:had been attributing to just general, you know,
Lilliana Lettieri:getting, getting older and perimenopause was
Lilliana Lettieri:really mitochondrial energy loss. That, that was
Lilliana Lettieri:really what was at the root of my symptoms. And
Lilliana Lettieri:the more that I did things to give my cells what
Lilliana Lettieri:they needed to be able to recharge and repair
Lilliana Lettieri:those symptoms just went away. And the other
Lilliana Lettieri:thing that I really learned was that there was a
Lilliana Lettieri:lot of screen time in my life and that it was, it
Lilliana Lettieri:was a huge part of the stressor that would
Lilliana Lettieri:trigger when I would, when I would struggle with
Lilliana Lettieri:the symptoms. So. Yeah. Wow.
Meredith Oke:And did, did it, did you connect back to when
Meredith Oke:you'd done your work with animals and how
Meredith Oke:everything about them was based on their
Meredith Oke:environment?
Lilliana Lettieri:Totally.
Meredith Oke:It's like for us, whatever, yeah, we're. I'll
Meredith Oke:just be on zoom nine hours a day. It's fine.
Lilliana Lettieri:Yeah, exactly. It was like it all just came right
Lilliana Lettieri:back and I was like, oh, our microhabitat is
Lilliana Lettieri:completely different from the microhabitat that
Lilliana Lettieri:we had 150, even 200 years ago. You know, it's
Lilliana Lettieri:completely different. And within that
Lilliana Lettieri:microhabitat that has a very different light
Lilliana Lettieri:structure. Let's say, you know, if you're to see
Lilliana Lettieri:what's around there, the wavelengths and the
Lilliana Lettieri:intensity of the light and all of that, it's
Lilliana Lettieri:completely different. And then within that, we're
Lilliana Lettieri:also additionally bombarding our eyes with a
Lilliana Lettieri:very, very specific cue that even though we don't
Lilliana Lettieri:see it in our eyes because it's not necessarily
Lilliana Lettieri:in the visible wavelength, our cells are feeling
Lilliana Lettieri:it, our bodies are feeling it, they are getting
Lilliana Lettieri:that signal through our eyes. You know,
Lilliana Lettieri:subconsciously, invisibly, secretly, whatever you
Lilliana Lettieri:want to call it, the body is aware of it. Even
Lilliana Lettieri:though we as, you know, organisms with a fancy
Lilliana Lettieri:eyeball that has some very fancy cones and rods
Lilliana Lettieri:that can help us attune to our environment. I
Lilliana Lettieri:think what we often forget is that there's so
Lilliana Lettieri:much information flying around on so many
Lilliana Lettieri:channels. And in order to survive, we as
Lilliana Lettieri:organisms, every organism, we actually have to
Lilliana Lettieri:filter out a lot of information. And that
Lilliana Lettieri:information is filtered out to help us survive.
Lilliana Lettieri:Right. There's only so much information we can
Lilliana Lettieri:process. But when that happens, I think we as
Lilliana Lettieri:humans with our big fancy brains, we start to
Lilliana Lettieri:think, well, this is just all I need to pay
Lilliana Lettieri:attention to is what I can see and what I can
Lilliana Lettieri:perceive and everything else doesn't matter or,
Lilliana Lettieri:or everything else that I don't need to pay
Lilliana Lettieri:attention to becomes inconsequential when the
Lilliana Lettieri:reality is our bodies are very attuned to
Lilliana Lettieri:everything going on around us.
Meredith Oke:Yes, yes. And when you. When you start to look at
Meredith Oke:it from the subatomic level, which we can't see
Meredith Oke:at all, but we know exists, it's like those
Meredith Oke:frequencies are like tractors driving through the
Meredith Oke:living room to ourselves.
Lilliana Lettieri:Right, right, Absolutely.
Meredith Oke:Okay, so how did you connect with Peter and
Meredith Oke:decide to, like, fully shift into. Into this as
Meredith Oke:your. As your main thing?
Lilliana Lettieri:Yeah, so Peter and I met when I was starting to
Lilliana Lettieri:look for just other people in the community who
Lilliana Lettieri:were doing something that I felt like I could. I
Lilliana Lettieri:could believe in. You know, like, I felt like I
Lilliana Lettieri:had been in this consumer electronics world for
Lilliana Lettieri:so, you know, almost a decade. I had really, you
Lilliana Lettieri:know, shifted my awareness to be like, this stuff
Lilliana Lettieri:is killing us. We need to do this tech better.
Lilliana Lettieri:You know, and it. I mean, you know, literally, co
Lilliana Lettieri:workers who had, you know, been very healthy,
Lilliana Lettieri:gone to the gym, they did all the things, you
Lilliana Lettieri:know, started to drop off because they had cancer
Lilliana Lettieri:and they had to, you know, just leave. So, you
Lilliana Lettieri:know, it. It was time for me to really look for
Lilliana Lettieri:something that. That made more sense to me
Lilliana Lettieri:professionally. And so I. When I met Peter, you
Lilliana Lettieri:know, he had already developed this amazing
Lilliana Lettieri:technology, and I immediately was like, I know
Lilliana Lettieri:how to build these things because this is what I
Lilliana Lettieri:do for my job. You know, I was project managing,
Lilliana Lettieri:building electronics that go in people's homes,
Lilliana Lettieri:working with the factories, working with the
Lilliana Lettieri:engineering teams, you know, making sure it's got
Lilliana Lettieri:all the features and all the parts that we need
Lilliana Lettieri:to get it out there. And, you know, I. When I.
Lilliana Lettieri:When we had our first conversation, I was like, I
Lilliana Lettieri:think we can. I think we can do this. Like, I
Lilliana Lettieri:think I can help. I can. I can bring something to
Lilliana Lettieri:the table here. So. So, yeah, I was excited.
Meredith Oke:Oh, that's so cool.
Lilliana Lettieri:Yeah.
Meredith Oke:Oh, I love this. Okay. So you brought all of that
Meredith Oke:valuable experience and knowledge and
Meredith Oke:understanding of supply chain things and all
Meredith Oke:that, that stuff.
Lilliana Lettieri:All that fun stuff, all that stuff that makes me.
Meredith Oke:Good night. But yes, it's very important if you
Meredith Oke:want to make things. I totally, I value that. So
Meredith Oke:you brought that to the table and then Peter
Meredith Oke:brought the technology, which so. And I love this
Meredith Oke:story. So, Peter, it's like one of those aha
Meredith Oke:moments. You're sitting in your office, you've
Meredith Oke:started to understand how important natural light
Meredith Oke:is. You realize that you're blocking out the
Meredith Oke:sunlight coming through your western facing
Meredith Oke:window in order to see Your monitor. And you're
Meredith Oke:like, wait a minute, what if the sun was the
Meredith Oke:light source for the monitor? Like, so. Good.
Peter Veto:Thank you. Good summary.
Meredith Oke:What happened?
Peter Veto:Much better than that.
Meredith Oke:So you had this epiphany and then what'd you do?
Peter Veto:Yeah, and then I. Well, I built it. I started to
Peter Veto:experiment, and I started with how many others
Peter Veto:have to remove the backside of an LCD to somehow
Peter Veto:gather daylight directly and channel it into the
Peter Veto:display? And first I wanted to use louvers. And
Peter Veto:that was an idea with which I experimented with
Peter Veto:and realized that in some cases it might work,
Peter Veto:but it will never work for any broader use case.
Peter Veto:And even in a single use case, it so much depends
Peter Veto:on the angle of the sun, which keeps changing
Peter Veto:throughout the day. And later, Ezai, a small
Peter Veto:startup, did a product which did something
Peter Veto:extremely similar, but instead of louvers, they
Peter Veto:just had the backside of the display to open. And
Peter Veto:then you can change that angle to hopefully
Peter Veto:channel more light from whatever direction, maybe
Peter Veto:from a window into the display. And it kind of
Peter Veto:works, but not really. So they also for their
Peter Veto:next round of products, immediately they moved on
Peter Veto:to rscd, which is then what Hisense and Sun
Peter Veto:Vision Display and Daylight Computer and all the
Peter Veto:others are doing. But nobody has really managed
Peter Veto:to get this daylight collection to work properly.
Peter Veto:And then as a next stage, I thought, okay, we
Peter Veto:have to concentrate sunlight. So I started with
Peter Veto:larger Fresnel lenses to collect light from a
Peter Veto:larger surface in the window and channel into the
Peter Veto:display. And maybe to try to direct them to with
Peter Veto:lens arrays, which can change the direction of
Peter Veto:daylight. But of course, again, daylight is very
Peter Veto:diffuse and it keeps changing its angle with the
Peter Veto:sun. So then sooner I realized that this is the
Peter Veto:same situation, just a little better. It might
Peter Veto:work, but definitely not in all the cases where I
Peter Veto:want it to work. And even then, you need to be in
Peter Veto:the window or very close for this to work. And
Peter Veto:then meanwhile, I moved back to Germany. I was
Peter Veto:doing another postdoc at Ulm, and I got some help
Peter Veto:from an optics professor at. And then it slowly
Peter Veto:became clear that really the way to do this
Peter Veto:properly is to collect daylight outside and use a
Peter Veto:fiber optic cable to channel it indoors. And then
Peter Veto:you can use it anywhere, and then you can use it
Peter Veto:in the basement, in a windowless office,
Peter Veto:anywhere. And it's going to be an intense light
Peter Veto:source, because the issue with all the displays
Peter Veto:is that you need much more light than what you
Peter Veto:have just from a reflective surface of the same
Peter Veto:size of your display, because it needs to pass
Peter Veto:through so many layers to give you the colored
Peter Veto:image. And because of that, any reflective
Peter Veto:display, any other daylight technology, will
Peter Veto:always look much dimmer than if you just place a
Peter Veto:white piece of paper next to it. So generally
Peter Veto:they are too dim. And that's also why the image
Peter Veto:quality has to be low for it to work. But if you
Peter Veto:can concentrate daylight, then you can achieve
Peter Veto:all the visual qualities of regular desktop
Peter Veto:monitors while using daylight, so. While also
Peter Veto:offering all the health benefits and comfort
Peter Veto:benefits of anything that is daylight. And so
Peter Veto:that's when it really started. 2019, I guess, the
Peter Veto:first prototyping. Of course, many iterations
Peter Veto:came, but that's when the concept started to
Peter Veto:solidify.
Meredith Oke:Okay, so I heard you describing this on another
Meredith Oke:call and you were like, oh, yes, all this
Meredith Oke:technology, we just do this. And I'm thinking,
Meredith Oke:I'm like, wait a minute, did Peter just say that
Meredith Oke:he's got a cable channeling sunlight into my,
Meredith Oke:into the monitor? And so the light coming out of
Meredith Oke:the monitor is full spectrum sunlight. I know you
Meredith Oke:mentioned you blocked uv, but other than that,
Meredith Oke:like, is that what's happening?
Peter Veto:Yes, it is. And of course it's not my invention.
Peter Veto:So these tools have existed.
Meredith Oke:This seems like amazing.
Peter Veto:No, no, no.
Meredith Oke:Sorry, you're okay. Yeah.
Peter Veto:These tools have existed for 60 years or more.
Peter Veto:The thing is that they have a very niche market
Peter Veto:because they compete with Windows. So they are
Peter Veto:adding a space. It is much cheaper and simpler if
Peter Veto:you just use Windows or even light tunnels. But
Peter Veto:for display, they cannot work, and that's why
Peter Veto:they are very useful. So I guess I just connect
Peter Veto:it to Fields and then what needed to be
Peter Veto:engineered by us, and the proprietary part is the
Peter Veto:backlighting architecture of Pixan. So how do you
Peter Veto:deal with a very intense and small light source
Peter Veto:and spread that light evenly on the back surface
Peter Veto:of the lcd, while of course also having an
Peter Veto:electric light source. You need that whenever
Peter Veto:sunlight is not available. And to have a
Peter Veto:standalone, fully usable display also for the
Peter Veto:nighttime.
Meredith Oke:Okay, this is just really crazy to me. So,
Meredith Oke:Liliana, how would you explain what's happening
Meredith Oke:here? And how did you first wrap your head around
Meredith Oke:it? Because I hear Peter saying, oh, there's been
Meredith Oke:versions of this technology where you put
Meredith Oke:sunlight through a cable. Really? There has been.
Meredith Oke:And like, could we people use that to light their
Meredith Oke:basements? But I'll hold that question. Just,
Meredith Oke:let's just stay focused on this on the other
Meredith Oke:monitor for now.
Lilliana Lettieri:Yes. So when Peter first explained it, I also
Lilliana Lettieri:kind of had to ask a few follow up questions. I
Lilliana Lettieri:was like, wait a minute, so you're, you're
Lilliana Lettieri:powering the monitor. And he's like, no, no, not
Lilliana Lettieri:with solar panels, solar collectors. So it's, you
Lilliana Lettieri:know, these lenses that are collecting and then
Lilliana Lettieri:concentrating light and then using fiber optics,
Lilliana Lettieri:which is, you know, in the communications world,
Lilliana Lettieri:that's what we use to bring in data instead of
Lilliana Lettieri:photons necessarily. But the, the fiber optics
Lilliana Lettieri:are the same, right? I mean, you know, my mind
Lilliana Lettieri:immediately went to, oh, yeah, you know, people
Lilliana Lettieri:used to put satellite dishes on their homes, you
Lilliana Lettieri:know, to collect information. And then, you know,
Lilliana Lettieri:we use fiber optics to bring data into our homes
Lilliana Lettieri:and then we connect it to our little. So it was
Lilliana Lettieri:like all the pieces made, sentiment, made sense
Lilliana Lettieri:to me. But when he said it, I was like, oh, yeah,
Lilliana Lettieri:that's what we should be doing. We should be
Lilliana Lettieri:using the sunlight to backlight the monitor,
Lilliana Lettieri:because the monitor has these very, very narrow
Lilliana Lettieri:wavelengths that are only indivisible. We're
Lilliana Lettieri:missing all of that, you know, beautiful,
Lilliana Lettieri:restorative, regenerative part of the spectrum.
Lilliana Lettieri:The part that you go out, you know, early in the
Lilliana Lettieri:morning to collect, to get everything going and
Lilliana Lettieri:healing. And, you know, people are now using
Lilliana Lettieri:photobiomodulation because we know that we're
Lilliana Lettieri:infrared deprived and all. You know, we know how
Lilliana Lettieri:to use fiber optics. We do it all the time. We
Lilliana Lettieri:call the cable guy to come. You know, like, yeah,
Lilliana Lettieri:it's not, you.
Meredith Oke:Know, it was just like, my brain is exploding
Meredith Oke:here. Okay, so we're just, instead of the
Meredith Oke:information that's bringing in our HBO or
Meredith Oke:whatever, we're switching to photons, which is in
Meredith Oke:which our information. Yeah. Okay. Okay. So if I
Meredith Oke:put one of these monitors in my house, how does
Meredith Oke:it work? Do I put something outside that connects
Meredith Oke:to it?
Lilliana Lettieri:Yeah. So there'll be a solar collector that would
Lilliana Lettieri:have to be placed somewhere, obviously, where it
Lilliana Lettieri:can collect sunlight and have access to sun at
Lilliana Lettieri:different parts of the day. And then a fiber
Lilliana Lettieri:optic cable would run similar to how you would
Lilliana Lettieri:conduit to run fiber optics when you have the guy
Lilliana Lettieri:come out and fix up your, you know, your home.
Lilliana Lettieri:Home network and. And then wherever you want your
Lilliana Lettieri:monitor to be, that fiber optic will then connect
Lilliana Lettieri:to this monitor through, you know, a regular
Lilliana Lettieri:looking cable. You plug it in just like any other
Lilliana Lettieri:monitor. And then throughout the daytime, you're
Lilliana Lettieri:just using sunlight. And then as the sun sets
Lilliana Lettieri:and, you know, if you, if you need and want to,
Lilliana Lettieri:as many people do need to use their monitor
Lilliana Lettieri:during the nighttime, we're still using LEDs, but
Lilliana Lettieri:just filling in that spectrum so it's more of a
Lilliana Lettieri:sunlight, you know, broader spectrum of light. So
Lilliana Lettieri:that you're still getting some of those healing
Lilliana Lettieri:wavelengths, but, you know, during the day,
Lilliana Lettieri:you're saving energy, you're getting all the
Lilliana Lettieri:healing stuff. You know, the win, win.
Meredith Oke:And then the. The lighting that you've put in
Meredith Oke:there at night, you've got actually taken into
Meredith Oke:account the biological impact of it.
Lilliana Lettieri:Right, right.
Meredith Oke:Okay. That's really crazy. So what if you wanted
Meredith Oke:to have, like, a lot of monitors, would you. Do
Meredith Oke:you just set up like a cable?
Lilliana Lettieri:Yeah, so. So there are many sizes of solar
Lilliana Lettieri:collectors that can, you know, concentrate enough
Lilliana Lettieri:light to run to, you know, you could go from one
Lilliana Lettieri:fiber optic cable up to probably 20. So depending
Lilliana Lettieri:on. If you're an enterprise that wants to just
Lilliana Lettieri:have one massive solar collector and hook it up
Lilliana Lettieri:to a bunch of monitors and maybe some light
Lilliana Lettieri:sources too, that can be task lights. That's
Lilliana Lettieri:possible, too. You can use it for task lighting,
Lilliana Lettieri:you can use it for ambient lighting. I mean,
Lilliana Lettieri:you've talked to some pretty amazing lighting
Lilliana Lettieri:designers now who they all are aware of this need
Lilliana Lettieri:for different types of lighting. And our monitor
Lilliana Lettieri:is arguably another type that we just. We use to
Lilliana Lettieri:work. We need to work with. And it's not. It's
Lilliana Lettieri:not a light bulb, but it's a light source going
Lilliana Lettieri:into our eyes and helping us work and helping us
Lilliana Lettieri:do our lives. So.
Meredith Oke:Yeah, and right now, I mean, we, very few of us
Meredith Oke:have a life where we don't need to be on the
Meredith Oke:computer sometimes, or want to be. I mean, I love
Meredith Oke:doing this. Here we are. But everything involved
Meredith Oke:with the computer, I'm continuously mitigating
Meredith Oke:its effects on my biology. So, like, right now, I
Meredith Oke:don't have blue blockers on, but I have the iris
Meredith Oke:filtering, you know, on one of the settings
Meredith Oke:that's filtering out some of the harsher blue
Meredith Oke:light. So, Peter, what you've created is a
Meredith Oke:monitor that's. We don't need to hack it because
Meredith Oke:it's actually. The light coming out is actually
Meredith Oke:good for that.
Peter Veto:Exactly. The mitigation is the right word.
Meredith Oke:It's the we don't. The blue blockers and the
Meredith Oke:filters and all that.
Peter Veto:Yeah, we have so many products to mitigate. And
Peter Veto:that just shows that there is a problem. Right.
Peter Veto:That none of them truly work, because that's why
Peter Veto:we have to keep using them. And still, it only
Peter Veto:solves the problem to some people, partially
Peter Veto:because digital eye strain itself can come from
Peter Veto:so many causal pathways. So some people have
Peter Veto:issues with the spectrum, some people have issues
Peter Veto:with the flicker, and it's very hard to figure
Peter Veto:out which one hurts you. And then there are all
Peter Veto:the invisible physiological aspects there. And
Peter Veto:then there are many visual aspects as well which
Peter Veto:go beyond just mere color vision. And so all of
Peter Veto:these together, you cannot mitigate for
Peter Veto:everything. That's great because now we have a
Peter Veto:huge choice of various surrogate products which
Peter Veto:we try to mitigate and people try to choose
Peter Veto:whichever suits them. But nobody can really
Peter Veto:tackle the root cause because that's not fixed
Peter Veto:until you actually change the light source. So if
Peter Veto:you filter out blue light from anyway very choppy
Peter Veto:and limited LED spectrum, then all that you have
Peter Veto:left is an even narrower part of even just the
Peter Veto:visible spectrum. Right. And that's why all the
Peter Veto:colors turn orange, which is just a color issue.
Peter Veto:With a better, broader spectrum light source,
Peter Veto:even without any blue light, you could have much
Peter Veto:better colors, which we do as well. For the night
Peter Veto:mode, happy to go more into details, but just to
Peter Veto:finish the previous thought, that cannot add back
Peter Veto:to the spectrum which what is missing. And then
Peter Veto:to add to the spectrum, let's say some infrared
Peter Veto:light, many people use extra desktop lamps next
Peter Veto:to the monitor. But again, that doesn't really
Peter Veto:account for what the issues with the monitor,
Peter Veto:with the slicker, with the other spectral
Peter Veto:problems. And it doesn't even necessarily reach
Peter Veto:those parts of the retina where it need to reach
Peter Veto:because you are still looking at the monitor. So
Peter Veto:the full VR is always doused in the light that
Peter Veto:comes from the display and not from anywhere
Peter Veto:else. And this is by the way, also an issue when,
Peter Veto:when you have a properly ambient daylit room, the
Peter Veto:vast majority of the receptor cells in the retina
Peter Veto:will be still doused in the light from the
Peter Veto:display and not from the room. Because the
Peter Veto:display is designed in such a way that it doesn't
Peter Veto:reflect ambient light. That's why you don't have
Peter Veto:glare and reflection. So that's important for the
Peter Veto:display. But since you are looking at around the
Peter Veto:center of the display and it's kind of large, the
Peter Veto:vast majority of the retina receives that light
Peter Veto:and not the daylight which might be in your room
Peter Veto:if you are lucky otherwise.
Meredith Oke:Right. So even if you have the window open or you
Meredith Oke:have a light box nearby supplementing the
Meredith Oke:spectrum, if your eyes are focused on the screen,
Meredith Oke:you're still mostly ingesting that.
Peter Veto:Yes.
Meredith Oke:And so it's also interesting what you were
Meredith Oke:saying. There's multiple factors like flicker,
Meredith Oke:which are, you know, these filters aren't
Meredith Oke:accounting for. And I think that's interesting
Meredith Oke:because I have personally noticed we get these
Meredith Oke:headaches on and off. And I do all the things
Meredith Oke:right, like I do all the things And I'm like,
Meredith Oke:where. What are these headaches? So I went to see
Meredith Oke:my chiropractor and I told her, like, I showed
Meredith Oke:her where. Where it was like on each side at the
Meredith Oke:base of my skull. And she's like, those are the
Meredith Oke:muscles connected to eye stream. And are you
Meredith Oke:spending a lot of time on your computer? And I'm
Meredith Oke:like, yes, well, some days, yes, some days, no.
Meredith Oke:But I do all the things. But what I'm hearing you
Meredith Oke:say is that there are so many layers to it. Like
Meredith Oke:there could. It could be the flicker. It could be
Meredith Oke:that maybe I need to wear my reading glasses and
Meredith Oke:I'm not.
Peter Veto:Yes.
Meredith Oke:What are your thoughts as an eye strain expert?
Peter Veto:Well, certainly not an eye strain expert. Thank
Peter Veto:you.
Meredith Oke:Yeah.
Peter Veto:And of course, I didn't want to say that it's not
Peter Veto:better if you can have the window open or can
Peter Veto:have some near infrared source nearby. And very
Peter Veto:interesting tie to Scott Zimmerman's work, which
Peter Veto:you have certainly presented here many times.
Peter Veto:That also this Clara collects and channels near
Peter Veto:infrared to the back of the eye. So obviously
Peter Veto:some near inference will reach also the fovea.
Peter Veto:But it's still different than if that is the
Peter Veto:light source that you are looking at. Right.
Peter Veto:Because. And especially the larger the monitor,
Peter Veto:the more it will block out basically the rest of
Peter Veto:your visual field in this spectral sense. Now,
Peter Veto:near infrared is also not focused so precisely on
Peter Veto:the retina, so there is definitely some scatter
Peter Veto:and some mixing there. But again, this is
Peter Veto:mitigation. Instead of having the right light in
Peter Veto:the most impactful lighting application that we
Peter Veto:have, because this plays out the only lighting
Peter Veto:application where the intended use is to look
Peter Veto:directly into the light source. And we do that
Peter Veto:for several hours every day. So it is really a
Peter Veto:concentrated and impactful application. And
Peter Veto:that's why I don't think we should look so much
Peter Veto:at even energy efficiency. Though obviously using
Peter Veto:daylight also saves energy, but that should be
Peter Veto:secondary because it's a little amount of light
Peter Veto:but going to the most impactful places.
Meredith Oke:Right. So, yes, for sure it's better to have the
Meredith Oke:window open in the supplemental, but when you
Meredith Oke:know. And that's a really good point. It's like
Meredith Oke:screens were designed for us to stare directly
Meredith Oke:into them, unlike light bulbs. And yet they were.
Meredith Oke:They did not take the physiological effects of
Meredith Oke:that into account at all. Like, not at all.
Peter Veto:Not even as much as regular light bulbs. So even
Peter Veto:regarding color rendering displays would never be
Peter Veto:acceptable as a light source for general
Peter Veto:lighting, because they have this narrow RGB
Peter Veto:spectrum optimized for the color spaces that we
Peter Veto:use in the online world, which is great. And the
Peter Veto:eyes are very easy to fool in that regard. So we
Peter Veto:can create a huge number of colors that way. And
Peter Veto:perceptual, it works very well. And actually,
Peter Veto:based on all the metrics that lighting uses this
Peter Veto:way, a modern display with high resolution should
Peter Veto:not be any different from reading a book. But
Peter Veto:then why do we have all the digital eye strain?
Peter Veto:Right. So that's the real issue that in the
Peter Veto:lighting world, nobody really wants to look at
Peter Veto:probably nowadays a little bit more. The trend is
Peter Veto:definitely changing, but traditionally the
Peter Veto:assumption was that all of this doesn't matter.
Peter Veto:But then it, it, you know, it flies in the face
Peter Veto:of the fact that so many people are struggling
Peter Veto:with this place and not with reading the book.
Peter Veto:The only difference is the light.
Lilliana Lettieri:Right.
Meredith Oke:Liliana, what thoughts?
Lilliana Lettieri:No, I don't think I have anything to add. I mean,
Lilliana Lettieri:I, I'm. I think Peter said it beautifully.
Meredith Oke:Okay, so is there a version of this where we
Meredith Oke:could get it, where we could have this work on a
Meredith Oke:television?
Peter Veto:Absolutely. It's the same technology. Yes. TVs,
Peter Veto:digital whiteboards, even VR headsets could work
Peter Veto:the same way.
Meredith Oke:I mean, this is really crazy because I think a
Meredith Oke:foundational premise that people who listen to
Meredith Oke:this podcast anyway have is that our screens are
Meredith Oke:just. They're just bad for us. And all we can do
Meredith Oke:is minimize our use and mitigate. And mitigate
Meredith Oke:what's coming out of them and do our best to work
Meredith Oke:around it. This is like a bit of a shift into the
Meredith Oke:idea that there's a way to do it. I'm not like,
Meredith Oke:advocating we should have more screen time in our
Meredith Oke:lives, but we all are going to have some at this
Meredith Oke:point. So this is really a shift to think about.
Meredith Oke:Oh, it could actually be not bad for us.
Lilliana Lettieri:Yeah.
Meredith Oke:Is that where you got to, Liliana?
Lilliana Lettieri:Absolutely. And even now, you know, just thinking
Lilliana Lettieri:of so many, you know, elder care facilities,
Lilliana Lettieri:medical facilities, you know, children in schools
Lilliana Lettieri:that don't have windows. I mean, there's so many
Lilliana Lettieri:ways that, you know, people that don't have
Lilliana Lettieri:access to. To sunlight to the extent that they
Lilliana Lettieri:need it, and they either need to be in front of a
Lilliana Lettieri:screen for whatever amount of time, or the screen
Lilliana Lettieri:could just, you know, be a tool to bring them the
Lilliana Lettieri:sunlight that they need to a place that, you
Lilliana Lettieri:know, that that's removed from the natural
Lilliana Lettieri:environment. I mean, there are, you know, you can
Lilliana Lettieri:go, you know, bunkers, you could go, you know,
Lilliana Lettieri:but, like, it doesn't need to be that extreme. It
Lilliana Lettieri:could just be an office space. Space Or a medical
Lilliana Lettieri:facility where somebody, you know, they're.
Lilliana Lettieri:They're not mobile enough to go outside and get
Lilliana Lettieri:the morning sun, but they can sit up in their
Lilliana Lettieri:hospital bed and, you know, watch TV or whatever
Lilliana Lettieri:and get that beautiful sunlight into their, into
Lilliana Lettieri:their, into their eyes, their brains, their
Lilliana Lettieri:skins, their cells.
Meredith Oke:This is amazing. Okay, so, so where are things
Meredith Oke:at? You know, like, can, can we order these right
Meredith Oke:now? Can I go back? Like, can we go byline?
Lilliana Lettieri:Not yet, but we're working really hard to get
Lilliana Lettieri:there. So we have some really amazing prototypes
Lilliana Lettieri:and we are currently talking to some promising
Lilliana Lettieri:manufacturing partners and currently fundraising,
Lilliana Lettieri:you know, to get that pilot build. I think we're
Lilliana Lettieri:gonna, we're gonna, you know, need a minimum
Lilliana Lettieri:order of at least a few hundred, if not a
Lilliana Lettieri:thousand. That's our goal in 2026, is to be able
Lilliana Lettieri:to build at least a few hundred and get them out
Lilliana Lettieri:to people. You know, hopefully with any luck,
Lilliana Lettieri:we'll be able to do pre sales to let people know,
Lilliana Lettieri:look, this is when they're going to be available.
Lilliana Lettieri:You know, you can get yours now and we'll deliver
Lilliana Lettieri:it in six months or whatever that turns out to
Lilliana Lettieri:be. So. Yeah.
Meredith Oke:Okay, so amazing. So how can we help? Can people
Meredith Oke:get on your wait list?

Lilliana Lettieri:that any listener can help is honestly just to

Lilliana Lettieri:getting people excited and talking about it is
Lilliana Lettieri:the biggest help. You know, like I said, we're
Lilliana Lettieri:talking to investors and, you know, raising
Lilliana Lettieri:money, raising capital right now to be able to do
Lilliana Lettieri:that initial production run. But the best way for
Lilliana Lettieri:us to show investors that there's excitement and
Lilliana Lettieri:there's traction and that people want this is to

Meredith Oke:are going to be really excited about this. For
Meredith Oke:those of you who are members of QBC Pro, Peter
Meredith Oke:and Liliana did a very deep dive into the
Meredith Oke:science. I know some of you really, really like
Meredith Oke:that. Keep it a little more high level on the
Meredith Oke:podcast so we don't scare away the new people. We
Meredith Oke:like you new people. Welcome. Come on in the
Meredith Oke:water's farm in the circadian world. But yes, I
Meredith Oke:want to make sure, because I know Peter, you
Meredith Oke:have, like, have some very, a lot of deep science
Meredith Oke:behind this. So if that is of interest to you,
Meredith Oke:make sure you're in the, in the QVC Pro
Meredith Oke:membership. That video is in there. Okay. Well,
Meredith Oke:I, like, I'm so grateful that you two are doing
Meredith Oke:this. Thank you, like, truly. You know, I've just
Meredith Oke:been noticing lately, like, there, there, we all
Meredith Oke:play a different role. Some of us are
Meredith Oke:communicators, some of us are scientists. And I
Meredith Oke:think the entrepreneurs and the people who start
Meredith Oke:companies are a huge, huge piece of it because to
Meredith Oke:be a successful company, you have to be. You have
Meredith Oke:to share the message and communicate it out why
Meredith Oke:you're doing what you're doing. So you're
Meredith Oke:spreading the, spreading the knowledge. So thank
Meredith Oke:you both. Any, any last thoughts you'd like to
Meredith Oke:leave us with? Like, I just want to say. So I did
Meredith Oke:really, I, I didn't really wrap my head around
Meredith Oke:what you guys were doing until I went to the, to
Meredith Oke:your website and you have a picture of the
Meredith Oke:monitor and a picture of the, of the cable and an
Meredith Oke:arrow that says sunlight in here to the cable.
Meredith Oke:That is very clear. And that's when the penny
Meredith Oke:dropped for me. I'm like, how? What?
Lilliana Lettieri:Yeah. Yeah. Awesome. Well, I'm glad. We had some
Lilliana Lettieri:amazing interns who really helped us up our game
Lilliana Lettieri:on the website and started us going on social
Lilliana Lettieri:media. Like, that's, you know, that's not my
Lilliana Lettieri:forte, but we're trying hard. So, yeah, I mean,
Lilliana Lettieri:the education piece is huge. Our mission, you
Lilliana Lettieri:know, alongside and in parallel to building a
Lilliana Lettieri:product that we believe in, that we, you know,
Lilliana Lettieri:that we have a mission and a passion behind is
Lilliana Lettieri:really education. I mean, we really have to be
Lilliana Lettieri:the storytellers and, you know, be the educators
Lilliana Lettieri:to raise awareness about the impact that these
Lilliana Lettieri:devices that we all have to interact with are
Lilliana Lettieri:having on us. So, yeah, I mean, if for no other
Lilliana Lettieri:reason than to just learn a little something here
Lilliana Lettieri:and there. Join us on the ride. We'll try to keep
Lilliana Lettieri:putting blogs out and educational content. I
Lilliana Lettieri:mean, that's part of it too. We just want to give
Lilliana Lettieri:people tools to help them heal and help them be
Lilliana Lettieri:able to survive in the digital world more in a.
Lilliana Lettieri:In a healthier way.
Meredith Oke:Yes. And everybody, like, this is. This is it.
Meredith Oke:Everyone's like, oh, what's going to happen in
Meredith Oke:the future? And we have a tech dystopia, or we
Meredith Oke:have a chronic illness epidemic, or this or that.
Meredith Oke:It's like, these are the moments. Like right now,
Meredith Oke:going to sign up for your newsletter to support a
Meredith Oke:company that could potentially, like, transform
Meredith Oke:the paradigm of screens in our lives. Like, we
Meredith Oke:all have agency here. We can all participate.
Meredith Oke:This is so fun and cool.
Peter Veto:Yes. And thank you so, so much, Meredith, for all
Peter Veto:your support. And you speak about these issues so
Peter Veto:eloquently, which we are just trying to learn to
Peter Veto:do, getting out of the academic silos. And so
Peter Veto:it's a very different convolocation style. And
Peter Veto:also here in this little conversation, you
Peter Veto:summarized what we were saying, especially what I
Peter Veto:was saying, so much better than we do. So there's
Peter Veto:a lot to learn for us. But till then, thank you
Peter Veto:so much for what the great work.
Lilliana Lettieri:Oh, thanks, Peter.
Meredith Oke:Thank you both. Thank you both for being here.
