•Jan 19, 20263 months agoSummary
Dr. Pam Theriot discusses the emerging dry eye disease crisis affecting children and adults due to increased screen time, explaining how reduced blinking causes oil glands to solidify and atrophy. She provides practical prevention strategies including the 20/20 rule, lid cleansing, warm compresses, and outdoor time to protect eye health.
Insights
- Dry eye disease prevalence in people under 30 has shifted from predominantly female (post-40) to equal male-female rates, directly correlating with increased screen use starting in early childhood
- Oil gland damage from screen-induced reduced blinking is cumulative over decades and can become irreversible (atrophy to 'nubs'), making prevention in early childhood critical
- Screen distance and gaze angle significantly impact both myopia development and dry eye progression, yet workspace ergonomics for eye health remain largely unknown to most professionals
- Outdoor time provides multiple eye health benefits beyond myopia prevention: long-distance focusing relaxes eye muscles, natural light regulates circadian rhythms, and environmental distractions naturally prompt blinking
- New imaging technology (within last 5-10 years) now allows detection and monitoring of oil gland damage, enabling early intervention before irreversible atrophy occurs
Trends
Dry eye disease shifting to younger demographics due to early childhood screen exposure (ages 2+)Emergence of specialized dry eye imaging and treatment technologies in optometry practicesGrowing awareness of workspace ergonomics as preventive health measure for remote/desk workersDevelopment of screen alternatives designed for eye health (grayscale, low-flicker devices)Integration of eye health education into gaming platforms and metaverse environmentsIncreased focus on preventive eye care products (lid wipes, warm compress masks, hydration supplements)Recognition of outdoor time as clinical intervention for eye health, not just recreationShift from treating dry eye symptoms to addressing root cause (oil gland dysfunction)Pediatric eye exams becoming recommended before age 1, similar to dental careBlue light and circadian rhythm disruption becoming mainstream health concern

Welcome to the 1000 Hours Outside Podcast. My name is Ginny Erickson, the founder of 1000 Hours Outside. And today's episode is incredibly important and really goes right along with what we're doing, getting kids outside. It is incredibly beneficial for their eyesight. And we've got this overload of screen time and screens that are really close. And so optometrist Dr. Pam Terrio is here, Ted X speaker. That's right, yes. Yes. And you have so many things that you offer, online courses, consultations, different guides. We're gonna be diving into kids and adults in our eyesight. Pam, thank you for being here. Thanks so much for having me. What is your background? And I love that you are really working with, you know, people go to the eye doctor, you know, for their own appointments, but you are actually going further than that and putting information out into the world about dry eye and about, I mean, I tried some of the tests where you like close your eyes and then open and see how long before you blink. And you're putting out all this really extra information. You have a blog with over 240 posts for people. Is it just because screens have become so present that people just need more? Well, I believe that our eyesight is our most precious gift. And if we knew better, we would do better. So most people, another podcast host told me she was an eye neglector. And I was like, yes, people just neglect their eyes, right? We brush our teeth twice a day, every day, wouldn't dream of going to work without brushing our teeth before we got there. And yet, if all of our teeth fell out tomorrow, we could just get new ones. And when was the last time that you actually put in effort to take care of your eyes? You know, some of us go to the eye doctor once a year, but for the most part, it's like a second. It's like, oh, I'm not seeing as well out of my glasses. I should schedule an appointment and kind of put to the bottom of the barrel. Where's what we do without our eyes? Isn't that interesting? Cause yeah, you go to the dentist twice a year. It's like sort of this built in maintenance, but nothing with your eyes. In fact, I've never been. Oh, wow. Never, never. Like, I don't know. So I did your test. You have this free downloadable guide seen clearly in the screen filled world and you have a lot of things you offer. I'll make sure I'll put them in this show notes. I'll put a lot of things for parents and things for gamers, but I try the thing where you like close your eyes and then you open them and you see how long you can open your eyes without blinking. And then it's like a little test. You know, if it's more than four seconds or less than four seconds, have you seen as an optometrist, have you seen there be more issues in relation to increased screen use? Absolutely. So the problem with screen use is two-fold in kids. Number one, kids hold the screens way too close and our bodies are lazy. I hate to put it that way, but our bodies don't want to make efforts. So in order for us to focus our eyes up close, we actually have to make an effort within our eyes to do that focusing. So kids become more nearsighted. The closer they hold things to them, the eye just grows more nearsighted, which is the lengthening of the eye and it happens over time. And some of us are nearsighted because our parents are nearsighted, but some of us are nearsighted just because we spent too many hours with something right in front of our faces, which is not how we were created. We were created to be hunters and gatherers and be outdoors and look far away and not constantly looking at something in front of us. So that's problem number one. And mostly it's for kids because in the developmental years, our eyes are able to grow. Once we're in our mid-20s, our eyes aren't really growing like our bodies. Our bodies aren't growing as much, our eyes aren't growing as much. And so you're not going to become quite so nearsighted. But so for kids, that's super important. But for all of us, any of us using screens, no matter our age, when we stare at a screen, our blink rate decreases. So we should blink about 21 times a minute, but when we are staring at a screen, that drops to one third of that. So about seven times a minute. Look at your face, you're shocked. And it's just the matter of like that we're paying attention. It happens a little bit when you're reading an actual book that your blink rate will decrease, but screens have this special ability that really trap our attention and we blink so much less. What does that mean? Okay, you're blinking less. So are your eyes really drying out when your eyes are open? Part of it is, yes, that the blinking is refreshing our tear film. It's keeping the mucus membrane of our eye lubricated. But what happens is that when we're on our screens, hours and hours a day, day after day after day, for decades, right? This is just something that happened yesterday, but it's because we're doing it every single day for as a lifestyle. The little muscles in our eyelids that control the oil glands aren't squeezing those oil glands and getting the oil to come out. When we blink, the lid should come together, a little bit of oil should come out of those glands and then it should spread right across the front surface of our eyes. And when you're not blinking as much, the oil in the oil glands starts to solidify. So it hardens, it's no longer like olive oil, it becomes more of a butter, and then it becomes like a Crisco. And using that analogy, we all know that olive oil is healthier than Crisco. So when that oil solidifies, it doesn't come out when we blink. We could even squeezing our eyes closed doesn't make the Crisco come out of our eyes. So then we don't have that oily layer of our tear film and our tears just evaporate even more quickly. Wow. No one is talking about this. Like don't solidify your eye oil. Like there should be billboards about this. Billboards all over the place so people can know, yes. So that knowledge is fairly new. We didn't have the capability to image those oil glands in our lids until within the last 10 years, but maybe within even the last five years. And most eye doctors just didn't have that equipment in their office to image these glands. The knowledge to know how to treat these glands, it's all very new in the healthcare realm. So now we know how to fix the problem, how to image the problem so that we can identify it and then treat it. There's still tons of research being done to know the best ways to treat it. How to even prevent damage in these oil glands to begin with. Yeah, the prevention is key, especially if you've got kids and you're dealing with screens. I remember when I was a kid, my grandpa would come over, we would be watching like shows after school and he would come over and he would grab us by the arm and we were like, you're too close. So even you, which is always remarkable to me, like in these older generations that they somehow had a sense, like you shouldn't be that close to that screen, you should move back. Well, now we've got iPads and phones and it's all right in our face. So, okay, I did the test, I got to six seconds, which actually was not great. So I was like not in the severe category, but I wasn't in the mild. It's just interesting, I did worse than I expected to. I've only read about this one other time and it was recently, Dr. Pam, I read about it in, I can't remember what book it was, but they were talking about how when the oil glands finally crap out and quit, like you're done. There's no coming back at that point. And so then they said people have to like artificially lubricate their eyes for the rest of their life. And it was like, oh wow, this is a bigger deal than I realized and something to pay attention to. So can you talk about the self assessment that you have people do? Because if they're in there, well, not if they're in their car because you're driving, but like if you're sitting around or your kids are sitting in the car, everyone can try it. Can you talk about the self assessment that you have people do? Absolutely, so what we're talking about is the inter blink rate. So how long can you hold your eyes in between blinks and averages 10 seconds? So your tear film should stay full and healthy on the front surface of your eye for at least 10 seconds. So what I have people do is super simple is that you're just gonna blink your eyes a couple times to kind of prepare. And then when I start counting, you're gonna hold your eyes open. So you're gonna blink, blink, blink and open. Two, three, four, five, six, seven, eight, nine, 10. Okay, I did it. All right, I feel better. Okay, so for my eyes, I around six seconds, I started feeling like a little stinging. I wanted to blink, but I held it. So those are the kinds of things to think about. So if that your eyes are starting to sting and burn, your tear film is evaporating. And that's how you're feeling that. So you should have a full layer of tears over the front surface of your eye. And as that evaporates, then your eyeball feels the environment. And that stinging sensation is an indicator that things are drying out. So is that how it would feel? Cause it feels uncomfortable and you just went a blink. Is that how it would feel or start to feel if the ducts, if the glands start to solidify? Absolutely, yeah. As there's less oil in your tear film, the tears just evaporate very quickly. And so yes, people who have this my bomean gland dysfunction or clogged up oil glands, their tears evaporate very quickly and that stinging and burning becomes almost constant and they're lubricating all day and just putting in artificial tears isn't always an equivalent to what your own natural tear film would be. Okay, this is a big deal. This is a big deal. So everyone needs to know about it. Can you talk to us about, and people would think what in the world can you talk to us about blinking exercises? Yes, so because where eye doctors came up with this, we decided to make it cute. We're going to call it the 2020 rules. So every 20 minutes, while you're working on your digital device, you should take 20 seconds. And the first rule was to refocus your eyes, look 20 feet away. So every 20 minutes, take 20 seconds to refocus far away. And this is really great for kids because as I was saying earlier, we focusing up close is an effort. And so if we focus far away, we actually relax the eyes. So have them focus their eyes across the room on a clock, make sure they can see the numbers on the clock or on the microwave. They can see what time it is all the way across the room and just do that for 20 seconds. But then when we got into the digital device area, we decided to add blinking. And so after you look away, then take some intentional blinks. So with blinking, you're going to squeeze your eyes closed and then open and just kind of like three or four really intentional blinks where you're really squeezing. That's going to really work those muscles, squeeze the oils in our oil glands and get the lids really closed. And you'll feel the difference. You'll feel a lubrication of the front of your eyes with those squeezes. But just taking 20, every 20 minutes, just kind of to blink your eyes purposefully can help. Okay. I mean, this is the first time hearing of this and it's really important. You talk then about ways to set up. You've got this incredible, I'm going to put a bunch of links in the show notes, but this is seen clearly in a screen-filled world. It's this free downloadable guide and you talk about how to set up your workstation. So this is for adults and kids. You talk about while you're working, try these micro blink, right? Micro blinks, micro breaks. Micro breaks for your blinks and you really have to be aware of that. But one of the things you talk about is you say this is extra credit. I've never even heard of this, a desktop humidifier. Yes. So if we just keep more moisture around us while we're working, especially in the wintertime here in Louisiana, it doesn't get that cold. But this week it dropped into the 30s for two days. I know you're more northern, right? So we turned on our heaters and because we can't stand it, if it's less than 60 here in Louisiana, so we turned our heaters on and now the air is dry. So it's very dry and to counterbalance, even in the summertime, you've got the air conditioner blowing on you. You want to be cognizant of, is there a fan blowing directly on your face? Is there event blowing down on you? That's just extra airflow drying out your eyes. So that desktop humidifier actually have one on my desk at home, but now I'm at work this minute. But just like it's a little bitty guy that you put some distilled water in, you sit it next to you, it's making some mist into the air and just keeping the air surrounding your desk more moisturized can really help. Yeah, just these small things, these things that you can do. I talked to this woman named Katie Bowman and this was like a phrase, like when you talked about what did the lady say? She said, she's an eye neglector. Katie Bowman used this phrase about long distance looking and it was one of the benefits of going outdoors. Like she said, when you're indoors, it's a short, even if you're in a room that's rather large, you know, it's this short distance looking, you stuck with the muscle around the eye relaxing. When you go outside, it's this long distance looking. So can you just, you know, it's tricky to get kids outside in this day and age from the standpoint of eyesight. Can you give parents or kids or grandparents or single adults who are listening, just a little encouragement that getting outside is good for their eyes? Absolutely. So that long distance looking is the opposite of what I was telling you when you have a screen in front of you, our eyes have to focus. And that's utilizing the eyes, the muscles around the lens inside the eye has to change the shape of the lens so that we can see clearly. And it happens naturally, you don't think about it, you don't feel it. But when we look in the long distance that completely relaxes our eyes or the most relaxed when we're looking in the long distance and it can feel good, right? You can be completely relaxed. You can go outdoors, you can get that vitamin D on your skin and it can energize you. So I was just thinking that we go out outdoors and we get the vitamin D which is gonna stimulate our circadian rhythms. Having the blue light on us from the sun stimulates our circadian rhythms and helps us to wake up in the morning and then shut down at the end of the day. Which is another problem that we have with all of our screen times and the blue light that's being emitted from them. So I'm kinda jumping topics there, but as I was talking about being outside in that long distance viewing, just having the sunlight on us is beneficial. Well interesting, cause all of this goes through the eye. I mean most of it, I think some light goes through the skin but for the most part, your eye is your gateway and so I had read a book that talked about how we look at the eyes and we think they're primarily for seeing but they're also for light, like so that your body knows what time of the day it is and what part of the year it is. Like animals, they're fur thickens and they have all of these processes that happen in part because light goes through the eyes and somehow tells the brain what the body needs to do. And so it is interesting that the eye, it's really the regulator for so much or it's the beginning of the regulator for so many things. So getting outside helps with that long distance looking but also with seeing what kind of light is coming in, what color is the light. I mean that color changes throughout the day. And that tells our bodies that it's time to wake up or it's time to shut down and talking about sleep disruption in all of us when we're staring at our screens and the blue light being emitted from our screens is disrupting our sleep when we're doing that when the sun is down. Because it's giving a false signal to the brain that oh, I need more serotonin because it's time to be awake and then we're getting into bed. A lot of people, last thing they do is check their phone one last time before they get into bed or they're reading something on the phone, they're watching something on the phone and then they get into bed and can't fall asleep. And it's not really because that what they were watching was so stimulating, it's the light that is stimulating. Not even the content. Yeah, so all of this goes back to the eyes. Spring has a way of filling up the calendar quickly. Field trip, sports, travel, co-op, which are all good things but they can make it challenging to keep curriculum learning consistent. March is really about maintaining momentum while life gets busy. That's why having a flexible organized learning tool can make such a difference in the final stretch of the home school year. IXL is designed to fit into your routine, not complicated. IXL is an award winning online learning platform offering interactive practice in math, language, arts, science and social studies from pre-K through 12th grade. It adapts to each child's level, keeps them motivated and gives parents clear visibility into progress. What I especially appreciate this time of year is how simple and time-saving it is. Everything is organized by grade and subject so you can jump right into exactly what your child needs. Whether that's reinforcing a concept before testing or confidently moving ahead. The clear explanations and visible progress markers help kids stay encouraged as they work toward year-end goals, make an impact on your child's learning, get IXL now and when 1,000 hours outside listeners can get an exclusive 20% off IXL membership, when they sign up today at ixl.com slash 1,000 hours, visit ixl.com slash 1,000 hours to get the most effective learning program out there and get to the best price. Okay, I have been waiting to say this. Wombikes is the official 2026 bike partner of 1,000 hours outside and it just makes sense because here's what I know, when kids fall in love with riding bikes, something shifts. They go from hesitant to flying down the sidewalk with total confidence and that confidence spills into everything else. These bikes are lightweight, thoughtfully designed and built so kids can actually succeed. The brakes fit their hands, the geometry fits their bodies, they feel capable right away and in a world pulling our kids towards screens, bikes pull them toward freedom. So we are kicking off spring with a 100 hour ride challenge and we'll release a special tracker to log 100 hours outside on bikes. And yes, at members, we're working on bringing that right into the 1,000 hours outside app. It's going to be so fun. If you've got younger riders, the womb GoBikes are perfect for beginners and come in six bright colors, including a brand new powder pink that just screams spring. If you're working toward your 1,000 hours outside this year, a great bike makes it a whole lot easier. Womb Designs lightweight bikes built just for kids so they can ride farther and ride happier. Go to womb.com, that's W-O-O-M dot com and use code OUTSIDE10 at checkout for 10% off your bike purchase, excluding the womb wow. Excluding the womb wow, that's OUTSIDE10 for 10% off at womb.com. Gaming is a big deal. I mean, kids are spending a lot of time on games and the games are really, they're really lifelike. They have all these video components, like these video segments from one section to the next are very different than the games look like when I was young. Can you talk about the gaming and the I say to similar things happening where the blink rate is going down and then talk about how people can transport from their game into a thing that you created that helps them to remember to blink? Absolutely, so what we're talking about here is that I'm developing a dry eye center in the metaverse and through the Fortnite game, you can transport from gaming within Fortnite into my dry eye center in the metaverse, which is awesome. Once you get into the dry eye center, we really talk about gaming and the eyes and not only blinking, but we want to prepare our eyes for the tasks that we're trying to do. So if, let's say we were going to run a marathon, right? We would car blow the night before, we would hydrate, we would train, we wouldn't go out and run 26 miles. We would start with one and then three and then five, you would build up to this and prepare our bodies for the task at hand. Unfortunately, all of us, not just kids who are gamers, but those of us who sit at a desk at work and expect our eyes to focus on the computer in front of us all day long, we're doing this without giving our eyes any support for the job ahead. So what I propose is that if we gave our eyes the support that they needed throughout the day that our eyes would help us to see clearly throughout our workday. So for kiddos, we built this gamer kit, which contains a couple of things. There's three items and they're super safe for kids to use. So the first item is a lid and lash cleanser. So this is the lid and lash cleanser box. It comes in these little pre-moistened wipes. So before they start gaming or after they're done gaming, they can pull this wipe out and just cleanse their lids and lashes. We all have bacteria that live on our lids and lashes and dirt dust debris pollen can get trapped in our lashes. That gives that bacteria a home to replicate in. And then we get an overgrowth of this bacteria. The bacteria, as I said, is supposed to be on our lids and lashes. It's normal to be there, but when it gets overgrown, it can cause inflammation on the front of the eyes. It can make your eyes more red. So if you wake up first thing in the morning and your eyes are bright red, it's probably that you have an overgrowth of this bacteria on your eyes. The bacteria also puts out toxins into your tear film, and then those toxins will help to solidify the oils and the oil glands. So it's a vicious cycle of having too much bacteria and those oil glands getting clogged up. So cleansing lids and lashes once or twice a day, super easy for kids to do. It's just a wet wipe that is created for the eyes. And then you rinse that off. The second is a warm compress. These are air activated, warm compress masks. So it's not going to be too hot. Now, being from Michigan, this was created from an eye doctor who's from Michigan. So it's called I-Duration. He took the hot hands idea and made it into an eye mask. So once you pull the mask out from the packaging, it starts to heat up. And the little pads here get hot about 108 degrees, which is the temperature to melt the oil in the oil glands. And then there's a little loop. So you just loop it over your ears easily. It stays hot for 10 to 12 minutes, which is exactly enough time that you need to melt those oils in the oil glands. But what I like about this mask for kids in general is that it's not going to ever get too hot. We have other masks available over the counter, even by that same company. I was looking to see if I had one. But you pop them in the microwave and then you put the microwaved mask over your eyes. So they're all made by Brooder. The Brooder warm compress that you microwave. If you microwave it too long, you could pop it all over the microwave. But there's beads everywhere. Or it could get too hot and then it would burn your eyes. So I love these air activated masks for kids because they're never gonna burn themselves. It doesn't get hot enough in the air to burn. Okay, and then the third product that we have in this Gamer Kit is the dry eye drink. So there's three little tubes of the dry eye drink. This is a hydration drink, no sugar added. So there's not a bunch of sugar that's gonna now hype your kid up. It's made with stevia. And then it has the minerals that support your tear film. So you drink this down, it increases your hydration. You just add it to a bottle of water, shake it up. It comes in mixed berry, strawberry, lemonade, and orange. And shake it up with a bottle of water and then the kiddos can drink this, give them that hydration, give them some vitamins and minerals to help them make a healthy tear film. And this purple one over here, this is actually the PM version. It has a little bit of melatonin in it as well to help kids get to sleep after all they're gaming. Okay, so you have that right on your shop and I'll make sure I'll put a link in the show notes on your website, you have a shop and there's a lot of things there. People can take online courses or if they can come in for consultations, these free guides. But what would happen? So if they're gaming, you're saying something could pop up and they could transport in the metaverse to this dry eye center. If they would transport, I would imagine that when the kid is in the thick of a game, it might be difficult to get them to transport but maybe that's just part of your routine. Maybe part of your routine is that you do the wipes or when you're done you do the mask or you have this routine around gaming because you know that you gotta make sure you're taking care of your eyes during the process. So they would pop out of their game and would it just kind of guide them through a quick thing of taking care of their eyes? Right, so that pops them into the dry eye center that I've built in the metaverse and then from there, there's a couple of places they could go but it's the same thing, it's like a guide of how to do these three steps or the shop where you could purchase this stuff and have it delivered to your doorstep or download the guide in PDF form. Okay, okay. So the kids are gaming, they're gaming quite a bit or just if kids are on their phones or different things like that. Can you talk about how young this is showing up? Is it showing up pretty young? What are you seeing with your patients? So what happens with those oil glands that are solidifying is that the long, the downstream effect is something called dry eye disease. Typically, even 10 years ago, dry eye disease was something that happened to women after the age of 40. There's big hormonal shift that we have after the age of 40, we create less moisture in our bodies and then women's eyes got dry. But today, the prevalence of dry eye in people who are under the age of 30 is equivalent male to female. So that is caused by the increase that we have in screen use. So men and women under the age of 30 are developing dry eye disease at the same rate which was pretty unheard of. Even 10 years ago, 30 year olds did not get quote unquote dry eye, but now because of that decrease in the oil production as these oils solidify in our lids, we're seeing more and more patients with dry eye younger. The other scary thing is that more doctors are routinely imaging those oil glands on the inside of the eyelids so we can see the atrophy. Funny enough, about five years ago, we got an imager in my office. And so me, myself and my lead technician were setting it up and training on how to take the images. So she's the one who takes the images most regularly. So I was the guinea pig, she took a picture of my oil glands and voila, I have perfect oil glands. I take really good care of my eyes, I clean them every day, I use my warm compresses. So I had great looking oil glands. Now my technician who is 20 years younger than me, roughly, her oil glands looked like crap, was crazy because I didn't get a cell phone until I was in my 20s. And so I didn't go to college with the internet. I went to the library and got books. So I don't have as much screen time in my youth, I didn't have any screen time in my youth and just don't in general spend as much time on my phone as a younger person would. So the problem is we're now giving our two year olds tablets, and phones, and they are looking at them for hours and hours and hours. And like I said, it isn't because you were on your computer yesterday that your eyes hurt today, it's because we've been doing this for 20 years or longer with your phone in your face for long periods of time. So now that we have this ability to image these oil glands, we can now identify and treat. There's new technologies that are coming through that have shown us that we can unsolidify the oils. Okay. And we can help to heal the oil glands. That is one of the things that I was wondering. Okay, is there a point of no return though? Some patients have nubs, nubs is all they have left to these oil glands, they should be fairly long. They should go the whole length of your eyelid. And sometimes, so from the lashes to the bone, upper and lower, you have about 30 oil glands on the upper and the lower lids, these oil glands. And in the upper lid, they're very long. But with the atrophy of these glands, as the oil inside the gland solidifies, then when you blink, it doesn't come out. And the oil gland goes, eh, you didn't make the oil I made for you yesterday. So I'm just gonna start to shrivel up and die. It's just atrophies over time. And the glands get smaller and smaller and smaller. So there are some treatments. Number one, that we can heat up the oil and express it out. So just like Crisco can become butter, can become oil. If we put it in a frying pan, you can watch it liquefy. That's what the idea of heating is doing. That's why I'm encouraging you to use a warm compress mask because you're gonna melt that solidified oil and help it to come out of the glands. So there are in-office procedures that you can do as well to really heat it up and squeeze it out. At home, there's no real way to squeeze it out ideally or easily. So just heating it up and blinking can get some of that clogged oil out. But in the doctor's office, there are methods that we can use to express the oil out of the glands. So that's number one. We can evacuate out all of the clogged oil. But now we even have some energy-based devices that can energize the oil glands themselves and help them to heal with light-based technologies. Right? Oh. It's always interesting to be exposed to a whole field that you're like, I had no idea. And yet I use my eyes every day all the time. And yet, obviously there are people that are looking into this because there are the imagers. I mean, the fact that someone was like, let's create this technology where we can create images of the glands and the oil glands and see if they're atrophying or see how healthy they are. There's definitely a group of people that are aware of this to the point where they're making these machines. What do the images look like? Oh, so everyone always says they look so ugly. But it's basically a black and white image where there are white lines. The white lines indicate our oil glands. Like I said, we flip the lid down and then I even have a handheld one now. It attaches to my cell phone. And so it's a little camera on the back of my cell phone that when you flip the lid down, you can aim it into the inside of your lower lid and then see the image of the glands. What? Wow. So if they haven't completely become nubs, can they regenerate? So there is evidence that with the energy-based technologies that we have, we can stimulate them to heal. There's been some studies to show there's growth by using something called intense pulse light or IPL treatment. Dermatology has been using IPL treatments to treat rosacea in the face. It shrinks blood vessels. But that same energy is used around the eyes to put energy into the oil glands and stimulate them to heal. Since we have a lot of moms listening to this podcast, maybe they've seen these red light masks that you put on your face that reduce inflammation. They treat acne. So it's similar to these LED masks that we're thinking about putting energy into the skin to allow the skin to heal, which is awesome. OK. But it's a hefty undertaking. And so what it seems is that the best thing is prevention. Right. And this is starting young. I mean, I really can't imagine being in your 30s and then having to deal with issues with your oil glands. You've never even heard of it. You're like, what's the? People come in probably because they're just uncomfortable. They make an appointment. Right. What are some of the things that they may be feeling? So generally, it's stinging and burning, feeling like they need to rub their eyes. Sometimes it's foreign body sensation. Oh, it just feels like there's something in there. Other times, it may be I can't wear my eye makeup anymore or I can't wear my contact lenses, my eyes are just so uncomfortable. They become red and irritated when I wear my contact lenses. And towards the afternoon, they become so dried out and irritated. I have to take them out. Or my eye makeup is so irritating that my eyes become red. And it waters a lot. That's another kind of funny side effect of dry eyes that the eyes are so dry that they water. The body is trying to flush out that sensation. So sometimes they overwater or they become super sensitive to smells, which is strange. But you put something that smells around your eyes and your eyes water. You can think of an onion or someone's perfume and the scent is so strong, your eyes are watering. It's similar. You become so sensitive to smoke, let's say. You go somewhere where someone is smoking or go to a campfire and now your eyes are pouring water to try and flush that out. When you tell people that or let's say in their 30s that this is dry eye and the oil glands are struggling, are they just shocked, surprised, have most never heard of it? Right, exactly. They're wondering how did this happen. And then they'll blame something that they did last week. Oh, I had a big project at work and I was on my computer for 12 hours. It's like, yeah, that didn't help. But it's because you've been doing this for 20 years. It's not because last week something big happened. But generally, it's like the straw that breaks the camel's back. These things have been happening slowly. We give our two-year-olds the cell phone to entertain them so that they don't scream their heads off while we're trying to have lunch. And then they're using cell phones every day from the age that we're two on up. And that's what's causing it, not that we're overdoing it on a particular day. And anyone who uses a screen, you just naturally, your body stops blinking as much. So that's so interesting. And the age to read, actually, I know they really pushed kids to read earlier now, but our kids didn't learn to read till they were seven. Some kids, naturally, if people allowed their kids to learn to read when they were ready to read, they might not learn to read until they're nine or 10 or even 12 is considered normal. Like the reading age is like three to 12. Anywhere in that range used to be considered normal. That's when you learn to read. And with more leaning toward, I think, six, seven and above. So there would have been a time period for most of history where no one was doing near work for the most part until they were six, seven, eight, where the eyes are starting to already be pretty formed. So what a difference. Yes, yes, exactly. And even though kids aren't necessarily reading on these screens, right, they're being entertained, they're watching things, they're having all of this near stimulus and fast-paced stimulus at such a young age. Right, which was not a thing at some point. I've only heard about it in terms of myopia. Right. And which also causes issues and can be a problem. It can come from different things. I know you talk about it can be genetics, but also it can also be caused by a lot of this near work or at least can be a factor to it. But the dry eye thing is just a whole other piece, dry eye disease to be aware of. I guess, and really thinking about that there was a time in life where young kids, up until elementary age, would not have hardly been exposed to near work at all. And so their eye health would have been better. What would you recommend? I guess, here's what I think. It's hard to combat the screen age. And to your point, it's like you're trying to get something down or you're trying to hop in the shower. I actually talked to this man who said that he had, he's like a pediatrician, so that, you know, I was dealing with all these moms. And then one of the moms said to him, how do people used to change diapers without a screen? And she said, you know, my kid is so squirrely, I just give him my phone and he watches SpongeBob SquarePants. Well, I change his diaper. And the pediatrician was like shocked. He was like, you know, an older guy, he's like, well, people would like talk to their kids and interact and I know it's difficult, but it's a short period of time. So, I mean, that's a one year old probably, you know, an 18 month old that's holding this screen every single time they get their diaper changed and watching this really near screen. I know it's hard, but I think having more reasons to say no is helpful. So this is another reason to say no. It is for the dry eye disease. You don't want your kid to be 30 years old and have dry eye disease. Give us some recommendations. And I like strong recommendations. Like, hey, there should be very minimal screens until, I mean, there used to be minimal near work until six or seven. Right, right, yes. So I am not a pediatric optometrist, but speaking from the dry eye side of things, I would say the best thing that any parent could do for their kid's eyes is clean them, which is ironic because we tend not to clean our eyes. So, you know, you wash your face and you squeeze your eyes shut as hard as you can. And that line where your eyes come together, the lid margins, never get cleaned. So getting a product from the, you go to the pharmacy and you walk down the aisle of artificial tears and they will have these lid wipes. That's what I would recommend, that every night they brush their teeth, they wipe their lids and lashes, rinse off this soapy sopiness from the lid wipe and, you know, hop into bed. So having that habit, to me, even more important than brushing your teeth because you can always get no teeth, but just cleansing dirt, dust, debris, pollen from around the eyes, keeping that bacterial load down, could really make a big difference. And these wipes are built for the eyes, so they're not gonna sting and burn. They're super simple to use. I do not recommend baby shampoo. 10 years ago, that was a thing, oh, get something very gentle for the eyes, baby shampoo is no more tears. And so that should be great. But research has gotten into, you know, what actually is healthy to have around the eyes. And that's why these wipes in the eye care aisle have been developed. So get something specifically made for the eye, from the eye care aisle at the pharmacy and cleanse your lids and lashes. I think just one simple step that we could start, you stand your kids up on the stool in front of the sink at the age of two and they're brushing their four teeth. You're taking them to the dentist by age one with my baby had two teeth in her mouth when she turned one. And there we were at the dentist's office. I'm like, what am I doing, right? Have they had an eye exam at that point? They should. There are initiatives to have kids get eye exams before the age of one, catching eye cancer, catching eye turns, things that could affect their long-term vision. You know, you're taking your kids to the dentist, take them to the eye doctor as well. Okay, so we do the wipes, which I same thing hadn't heard of them. I also really like the name hydration. I think that's very clever. The hydration basket. Who are you? He's from Michigan. Yes, and I'm telling you, he's from Michigan. They are so clever. You're like, did the idea come to them in the shower? They're like, we could call it hydration. I love that. Okay, but also being aware of near work for young kids. Yes, and having them just push their screen arms length away. As far as their arms can go, the screen should go that far away and keep on them because tendency is they're gonna pull it in, they're gonna pull it in, they're gonna pull it in and just push it back. I have children myself. My 10 year old will sit that screen right in front of her face and I just push it all the way back to her knees. Mom, stop. And I'm like, I don't care. I will be that annoying. Yeah, that's what my grandpa was doing back in the 90s. I mean, he would come and just pull people away from the television. He said, you're too close. It's not good for your eyes. So at some point there was like this innate wisdom that people knew this wasn't good for you and then the screens have just gotten closer and closer and closer. For the adults that are listening that have desk work, which is a lot, that is another big change, Pam, isn't it? I read a statistic and I don't remember the exact numbers, but at some point in time, at the turn of like the 1900s, there was a large percentage of people that worked outdoors and certainly did, Andy Crouch calls it three-plane people where they moved in three planes up and down and side to side for their jobs. So if you're a plumber, you're a construction worker, you're moving in all different ways. I would imagine even if you're a doctor, you're working with people and you're moving your body and like you're in that city in front of a computer, you have patients. So there's certain types of jobs that you're not sitting at a desk and then there are now a whole lot of jobs where you are. And I don't know if that will swing back with AI, like is AI gonna take a bunch of the jobs that people just sat staring at their screens and now we're gonna have to go out into the world again and do other things, but can you give some advice? I know this is in one of your downloadables, but on how to set up your workstation. So for the person who's listening like me, who's not heard of a lot of these things and hasn't really considered how does this workspace affect my eyes? Can you talk about, like set it up how far should the computer be away? You talk about font size, you talk about colors, you talk about lighting. There's a lot of things someone could think about. Absolutely. So first thing would be the distance of your screen. So you should be further than your arms length or just at your arms length. So as far away as you can get your screen, again, that's just gonna help you're focusing further away it is, the easier it is for your eyes to see it. So some people need to be able to touch their screen throughout the day, but if you can put it at that, that arms length distance versus closer, the better. It should also be in a downward gaze. Now, if you're over the age of 40 and you wear a bifocal, then you know that the reading portion of your glasses is at the bottom of them. So having your workstation set up so that you're looking down into it versus up at it, that's bad for your neck. It's also bad for your eyes because as we're looking up, the upper lid doesn't cover as much as the eye as it should. And another fun fact is that your eyelids are there to protect your eyes. So they have a function and should be in a certain position. When we are looking up, we're exposing more of our eye and it can dry out faster. So in a downward gaze, your lid is actually gonna come down a little bit more, focusing at your desk and making it easier for you to look. The third thing would be lighting. Comment, no? Lighting. I know, I guess the whole thing is so interesting to me, Pia, I'm like, I've never heard any of it, you know? Right, you just go to work and it's like, there's your computer, okay, get to it. And for kids, you know, like ed tech is such a huge thing. And so, you know, we started using computers, like in, I think in the fourth grade, it was like an Apple computer and we would play, it's like a pioneer game where you try not to die of, I can't remember what it's called. People are probably like, oh yeah, Oregon Trail. You know, so like this one, and you learned how to type. And so I just think about how many decades of life I've lived where no one's been like, have your eyes gazed down. That's like an easy thing to do. Right, yeah, just pull your chair up enough so that you're looking down at the computer screen. Which is huge. The next would be lighting. So where are you getting the light from? You wanna have adequate lighting, but you don't want to be having it come straight at you. So behind or above is better. You can also think about glare. If you're fighting the glare from your screen constantly, it's giving you eye strain and irritating. And then within the screen, setting up your colors, do you want as much contrast, black letters on a white background, white letters on a black background. But if you think of something that's not as contrast sensitive like yellow and blue, that is going to create more difficulty for your eye to distinguish the letters. So pick something that has good contrast. Font size should be 11 or larger. And the font that you're using, if you're using something that's curly and cursivey where you're having to really focus on is that a G or is it a Q? I can't tell which way the tail goes. Just being aware of using a font that's easy to read can help your eyes make things easier. I talked to these people that created a product called Daylight. So they have a computer and they also have a tablet. And I mean, it's fairly boring. Everything is in gray scale. It's meant to not be addictive. And it's meant to be good on the eyes. And it's meant to not emit a lot of EMFs. It's no blue light. It works really well outdoors with the sun. So you could take your work outdoors, which that's such a great idea because you just automatically like you hear the birds. So you're going to look away. Like there's these natural, you know, you don't have to set a timer. You're going to naturally kind of look up and see what's happening. But one of the things that they talked about was Flickr. And I know that's one of the things that you talk about as well. The screen looks like it is one continuous image, but really it's flickering really fast. And that's what's making it look like it's one continuous image. Can you talk about how the newer, is it better to have a lot of Flickr, less Flickr? Yeah. So the higher Flickr rate is actually better so that it does look seamless, more like a television. To calm your system. And I think that kind of goes back to what your grandpa was doing, pulling you away from the screen. So it used to, I don't know if there's any truth to it because this is before my time even, but people thought that those big box televisions emitted something, some rays from the television that were harmful. And so like my parents would also tell me to, you know, sit further away from the screen. You know, that's no longer true that there's waves coming out of our televisions or our computers that are harmful to us, except that they're emitting blue light. And so that, in that idea, it is true. Blue light, it comes from the sun. That blue light's purpose is to stimulate our serotonin and to tell us to wake up. And at the end of the day, we should have less blue light so that our bodies know that it's nighttime and we can calm down and our melatonin can uptake again. So, you know, even though there isn't some cancerous wave coming out of your computer, you are getting that blue light. And I think that's probably what the makers of that gray device you were talking about is that it's not emitting blue light and stimulating. It's not, right? Right, and the thing, there's no flicker. I don't quite, I might be misremembering, but they have a lot of things that just make it way healthier for adults and kids and they have a tablet and it's pretty cool. You know, you can draw on it, you can take notes. It's a fantastic alternative, I think, to what's happening. I think people can get it with like their school money. If they homeschool, sometimes in your state, you get school money, so you can get it with that. So that's called daylight. Let me ask one last thing because, you know, we focus a lot on screens, but I really like to read. And I think that reading is a great alternative to screen time. You know, your child can build their imagination and you can really bond together. But obviously there are some similar things, like you said before, about the blinking. Are the rules or the suggestions somewhat similar? Like the 2020, obviously when you're reading a book, you tend to be looking down, not up. You got the book in your lap or something like that. Can you give any advice for kids who really love to read? Oh, I love kids who love to read. So of course, so reading a book, you're going to blink a little bit more than you do on a screen. So it is better in that regard. A book is even better than a Kindle. Try to get the paper white background instead of it being backlit. Try to get the paper background. But okay, let's say you're reading a book. So same thing, you want to push the book as far away as possible to cut down on becoming more nearsighted. You do want to take breaks so that you can breathe, focus your eyes and look away. The good thing about a book is that it has pages. So there is an end point. You could say every four times I turn the page, I take a break. Every time I get to a chapter, I get to a break in the reading, it's time for me to just look away, blink a couple of times and come back to it. Reading outdoors is easy because there's no glare off of your book. So go outside and when you hear the birds chirping, use that distraction to look away, refocus your eyes, try to find the bird in the sky. And get outdoors, right? Take a lap around the tree. There we go, there we go. There we go. Okay, clinical director of the Dry Eye Center at Lusk Eye Specialists. I'll put the link to your website, which is Pam Tyrio, but it's both T-H, which wow. It is the riot. Wow. Well, it spelled the riot, but the fact that it's pronounced tear is so perfect because that's what we're working on, right? That is incredible. Okay, so people can watch your TED Talk, is that correct? Yeah, it's a TED Talk, all of that screen time. Yeah, so they can watch your TED Talk and then really there's so much there. All of these blog posts, and I'll make sure, like I said, I'll put the link there so people can find it. But if they need consultation, they can get a hold of you and if they want to find these different products that you talked about like hydration, which is so clever, they can find that. I met a bunch of online courses, a lot of things there. And I'm so thankful. I'm so thankful that you have helped to expose all of us to something that we may not have known about. I didn't know about it. I knew about the long distance looking, I knew about myopia, and I just read recently about the losing the oil glands and then having to use like artificial tears for the rest of your life, but I didn't really understand how pervasive it was, how it's going younger. Like I didn't know all the details to it. So I'm so grateful that you came on and talked and I know people will get so much out of it. We always end our show with the same question, the question is what's a favorite memory from your childhood that was outside? Oh, I loved riding my bike. So me and my girlfriend who lived a block away, I would ride my bike to her house and then we would tear through the neighborhoods, just street by street. For hours and hours, we built ramps or we would hop our bike, you know, a foot up off of the ground and we get all the neighborhood kids and just ride our bikes around for, until the street lights came on, right? That's how you knew that it was time to go home. Isn't it interesting like even that, you know, that you got the wind in your face so you're probably blinking a lot. Like all of the sort of natural parts of childhood and the way that we grow up would, they would help make a more robust eye health. And so we added all these artificial things and they affect it. And so you just have to be more aware. But I still appreciate what you're doing because I mean, I've been studying this stuff for a long time and I didn't know. So it's a brand new thing for me to learn about and to be aware of. Everybody can go get the free downloadable guide seen clearly in a screen-filled world and try with your kids the self-assessment. The quick exercise to evaluate the impact of screen use. And people can see how they're doing. Send us a message, I'd love to know. Dr. Therio, thank you so much for being here. Thanks for having me, Jenny. It was fun.
