This is a YouTube video titled "How Toxic Chemicals Affect Your Vision | Dave Mark Bell x Dave Asprey" created in August 2024. The content features a detailed monologue or interview-style discussion primarily by Dave Mark Bell, focusing on how environmental toxins and lighting conditions impact vision and eye health, including practical advice on eye care and vision training. The discussion includes technical explanations about light types, eye strain, and methods to improve vision naturally. There is no indication of Alicia Mackey Huber participating in this conversation.
Chapters
Quite often you get exposed to a neurotoxin, your vision changes. There's something called a visual contrast sensitivity test, which you can get at certain eye doctors. And it measures. Can you. Can you see the difference between these 64 shades of gray? And if your nervous system is dialed in, you can see it, and if it's not dialed in, you can't see it. And they all look the same to you, or you don't see any gray at all, and it's totally invisible to your conscious mind. But when you say A versus B, oh, what the heck. So this is used to diagnose environmental toxins. And I have seen people, including me, like, I do something wrong biologically, the next day, I'm not 2015. One eye or both eyes may be blurry. And then I've even had times where, wow, that fine print is off. That's weird. But it gets better when you remove toxins and you increase mitochondrial function. Right. So some of this may be that. So when you had this sudden appearance of, you know, of nearsightedness, did you move into a new house? Was there any environmental change that would have changed the toxic load on your body?
Not that I'm aware of. I'm trying to line it up with, like, when it happened. Yeah. Nothing that I'm conscious of.
Okay. Do you practice dimming your lights at night?
I have been for maybe, like, the last couple months, so I haven't been.
Okay, so it's a new practice for you? Yeah. I'm seeing more and more problems with just eye overuse. Your eyes are not meant to see bright lights at night. It's like candles, fireplace, or fireflies and stars and the moon once a month. That's. That's the entire history of our species until recently. So dimming those lights, it takes time. Replacing crappy lights is a good thing. And you're in your podcast studio, right?
Right. Yep.
What's shining on you right now to make you look so beautiful?
Yeah, we got some pretty bright lights shining on me right now.
And they're LED lights, right?
I believe so.
Yeah. So they're kind of flat panels, kind of bright, harsh light. Okay. How much time do you spend under those lights every week?
Quite a bit.
Okay. You wondering why your eyes are having problems? Okay. Very bright, pinpoint sources like those, they actually cause skin aging in addition to eye aging. So there's people who I actually support who will, say, wear sunscreen indoors or long sleeves to avoid tissue aging from harsh LED lights, especially studio lights. Now, sunscreen is generally not Good for you because of its hormone disruptors and all that. So this is mineral type of sunscreen. That, that isn't the harmful stuff I'm talking about. Or maybe paba, the B vitamin based stuff. So what I'm doing that's different than you is I have 120 watt halogen over there and 120 watt halogen over there. In front of them is a diffuser screen. So basically my eyes are seeing two sun shaped orbs about this big. They call it diffuser screen from Amazon. For some amount of money at least put that in front of your LEDs. But, but your life will change if you just get a halogen. Yeah. They're hotter and they use more power and you need to change the bulb every now and then. Who cares? It's a hundred dollar lamp. But halogen makes a huge difference because it's warm and because there's, there's infrared light in it. The other thing you can do to, to, to chill your eyes out a bit, having a red LED light on somewhere makes a, a really big difference for you even if it's just behind your monitor. So you're just changing the ratio of the, this bright stuff. The eyes are expecting the rainbow of spectrum and heat to come from light. There should always be outdoors in the sun. There's heat and light together. When you get light without heat, the eyes actually don't turn on some of the healing stuff they should do. But I don't think you're going to turn on a radiant heater. I certainly don't do that. But if you look behind me there, see that red light that just came on behind me? Yep. At night those things are on. And I have something similar behind my monitor so that there's just a little bit of a red glow. Okay. You're like Dave, you're the biggest nerd ever. Look, you're on a low carb diet, right. It's cuz too many carbs do bad things to you. Okay. I'm suggesting you need to change the ratio of red light to blue light and infrared light in your life the same way you did with your food. And that when you do that it's going to create long term advantage for you. Okay. It's not as crazy as it sounds when you look at it through that lens. Right? Right. Okay. The next thing want to do is go back to that training I did. The stuff I learned from Myers Schneier. We talked about that resting of your eyes. They call that eye cupping. And guys, you can Google Bates Method. You can look at Meer Schneier's book M E I E R S C H N E I R. One of the more inspiring books ever. You realize what this guy went through to retrain his brain? It's nuts. And it is tiring to do brain training. I have 40 years of Zen that does that. But training your eyes is just as tiring. So I brought something for you. This is actually left over from my eye training years ago. I would refer you guys, but the guy who did that is not there anymore. Like they don't do that. So what I have. And a functional eye doctor or someone who does neurological eye training or a developmental ophthalmologist can do this. Can you see these little letters?
I cannot.
Well, that's because you have eye vision problems. Noses, right. It might be a camera issue. It's just like a grid you would use for searching out a word finding game that you'd find, but they're pretty darn small. And I have a smaller one and a bigger one. So what you do with the nearsighted training or, sorry, the farsighted training is to train your up close vision. You have these really, really awesome little things. There are lenses that have different levels of focus, kind of like readers, right? But if you wear readers all the time or corrective lenses all the time, your eyes get weaker and weaker by design. Now, every eye doctor who recommends glasses. How dare you say this, Dave, don't you know, guys, I have some information that you may not have. And yes, I wore glasses for the first, whatever, 20, for at least 15, 17 years of my life. I haven't needed them ever since. And I know dozens of other people who've been able to train their eyes. So you can say it's impossible. I have evidence that it's possible. One of us is right. And one of us probably is wearing glasses. So there you go, right?
