After it fuses for some time, it turns into a red giant, which will kill the planets Mercury, Venus, and earth. After a millions of years, the outer skin of the star will collapse onto itself, and become a white dwarf. That white dwarf will burn for hundreds more, until it becomes a black dwarf.

One factor you didn’t address is that when outside you’re essentially doing “far work” and flexing your eye to focus on things in the distance.

So one of the things I deal with is called keratoconus. It's basically where the keratin in your eye gets too weak to be able to hold its shape properly. This creates peaks and valleys (it can turn your eye into a cone, hence the name). It's basically super astigmatism. A newer procedure they do is basically dropping riboflavin drops in your eye and hitting it with a UV light. The riboflavin & keratin crosslink, creating much stronger keratin. It doesn't reverse the damage done, but it does help prevent the disease from progressing. I recognize that this video is old, and I haven't done a lot of looking into the history of the procedure, but I wonder if the studies done about myopia are related to the crosslinking procedure.

What you are describing is not keratin, it is the cross linking between collagen fibers. We will never perform lasik on a keratoconus pt, glasses will only help mild cases and usually the best achievable vision is attained with hard contact lenses that help to fix the optics of the cone shaped cornea.
Reading doesn't damage your eyes, that's near work. As long as you're exposed to sunlight it doesn't matter what you do, if the studies are correct that is.

Wearing glasses and our heavy reliance on them is simply beyond an inconvenience. Glasses are cumbersome, or impossible with some forms of physical activities/sports and can even deter people from healthy exercise. The other alternative is using contacts which you can't even wear if you're a person who has drier eyes and they also need to be constantly purchased, washed/replaced and taken out daily or before sleeping/napping. Lenses are also designed to be viewed only from the center and correcting even moderate amounts of myopia with any kind of lenses causes distortion (slight fish-eye effect) around the edges and corners that scales worse with the degree of myopia you have. While you can adapt to this distortion and regain your depth perception, the way you see everything with lenses will *always* be distorted. Then there's laser eye surgery, which you can't get under the age of 18, is still very expensive, and not everyone is physically eligible for. You might not even get great results after the surgery and there may be complications. This is an epidemic indeed, and more people should care.

+KitMellow What I don't understand is what actually makes your eye sight worse. I've realised I'm near sighted for a while, but I didn't get an eye test for whatever reason until a week ago. The doctor said that myopia is mainly due to genetics, but doing near sighted activities also play a role in worsening your eyesight. However he also said that I have become increasingly near sighted due to the eye strain I have by not wearing glasses. On one hand he's saying doing near work makes you near sighted and on the other hand he's saying looking at things far away also makes you near sighted.

That's what they all say. I've heard the exact same things from many different optometrists. Getting glasses earlier (in theory) slows down the myopia process, but it still worsens regardless if you wear these glasses or contacts. Yes genetics can play a role, but it seems to be a much smaller influence than people think, because I know people with parents that never wore glasses but are still myopic to some degree and some even some deeply myopic themselves. And then there's people who have plenty of outdoors/sunlight but can still have nearsight/farsight problems. It's 2016 but nobody seems to know what the actual determining factors are... We know the *theorized* risk factors, but it doesn't really help right now when the need for glasses is scaling faster than the human population is growing.

I am some degree of near-sightedness. I have no idea anymore how much so because, about four years ago, I sat on my glasses and broke them. I was stupid-broke. And it was about that time, that I started to work outside full-time. At this point, I don't really need them anymore. I just always figured my laziness and brokeness made me adapt to the eyesight I had. Who knows- it could've been the sunlight. I guess I should eventually go in to get my eyesight checked but you know - the only time I really noticed that I was near-sighted was while in college, trying to read the whiteboard under harsh fluorescent lights across the lecture room. When I'm outside, I can spot a hawk carrying a mouse from across a field. So - you know. Anecdotal but my experience. I guess it just depends.

i was told going outside was very important for stopping nearsightedness, but they said nothing about sunlight. its more about the fact that your looking around a f'load more than if you where indoors. and focusing on near and far objects in your environment rapidly all the time. the eye is a muscle after all so it makes a lot more sense than sunlight being the reason

Thus meaning that sun exercise and fresh air all play a part whereas indoor activities such as video games (which are specifically designed to promote dopamine release) potentially desensitize your body to dopamine. But this is speculation as an dopamine sensitivity in the eye and dopamine sensitivity in the brain arent necessarily linked.

Kirk Turner Did I attempt to defend either of the movements that you mentioned? My point was that neither the BLM movement nor the third-wave feminist movement is a representative sample of the population. To say that characteristics of either group can be used to draw inferences about the general population is a fallacy, as I previously mentioned. "I said no such thing." I pointed out a statistical trend, and you offered nonrepresentative groups as counterexamples. Because trends frequently have outliers, one cannot use isolated examples to show a trend. However, if your argument does not include "stupidity is increasing" or "intelligence is not increasing," then the misunderstanding is my fault and I apologize. "You have improperly inferred such a fallacy to so you can go all SJW." You do not know my motive(s), and even if you did, they are irrelevant to the validity of my argument(s). Claiming that motives are relevant - which I am admittedly unsure if you did, but I mention this just in case you did - is a fallacy because it attacks the source of an idea instead of the idea itself (study.com/academy/lesson/attacking-the-motive-fallacy-explanation-examples.html). To assess whether or not stupidity is increasing, one must repeatedly take a random sample of the population and find the average IQ. Then find the trend, as Flynn did.

Probably about ten don’t wear glasses/contacts on the regular, but several of those people have glasses they sometimes wear and are technically prescribed to wear, or simply refuse to get tested despite not being able to see what’s actually written on the board. Point is, there’s a very clear contrast between two groups of kids who grew up in, generally, similarish circumstances. The kids who likely spent far more time in childhood outside are less likely to have eye issues, while those who spent more time inside and less outside are far more likely to need glasses.

And they will keep pecking at a blood spot, up to and including killing the bleeding chick. So, glasses or goggles would be a vast improvement to letting chicks get pecked to death.

I'd like to see some data about "this wasn't a problem in earlier times." The literacy rate in earlier times meant that more people didn't wear glasses not because they didn't have myopia, but because they didn't need to do any close visual work, like reading. In almost every society, eyeglasses become more available to regular people starting almost around the same time that people start moving from rural areas into cities and suburbs. This includes the shock industrialization and commercialization from a previously agrarian China. I think myopia has always been a problem, but we're just addressing it more now because there is more demand of people who realize they could see better if they did something about it. Literacy rates are now higher and text on devices are now smaller. We get ourselves glasses and other eye corrections more now not because we need them more, but because of FOMO.

I… don’t think the original comment is describing myopia. I can see very clearly from 2cm away to 10cm away, I don’t need glasses for that. As a kindergartener I could see from 2cm to 50cm away. Literature is easy with myopia, outdoor work is hard. Even just errands. Myopia means anything far away is a giant blur. That was always a danger and a problem for me, because it’s literally unsafe to walk outside without wearing glasses. In medieval times I would likely have died as a peasant child, expected to work and play outdoors but unable to see obvious dangers in my way. So since I was four years old I had to wear glasses in the playground and learn to not drop them, but I could rest my eyes from the glasses when doing homework (tracing lines, practicing writing letters, and working on assigned reading). Far-sightedness, on the other hand, was unlikely to be a problem except for maybe seamstresses, scribes, illustrators… I can’t think of many medieval occupations that would be seriously affected.

there's a difference between dopamine released in parts of the brain vs released in the eyes. that's like saying "so if i do squats will my arms get buff?"

Actually, the video actually does talk about dopamine released *in* the eye -- there is dopamine and dopaminergic cells in the retina. It is certainly good for you to be happy, but it doesn't follow that it has an effect on myopia. It is possible, but atm we don't know. I mean, doing squats may affect arm buffness in some ways, but you want to do additional things if your goal is buff arms.

Of course staring into the sun will hurt your eyes lol. And the reason why it gets elongated might very well be its effect; while you cannot see much farther away from you, people who are indoors often don't really have to look far away , so your eyes might develop in a way more geared towards near vision. I would say that nearsighted people might very well have a better "close eyesight" than non-nearsighted people, probably.

I started getting symptoms of depression at 8 years old, also the same time as when I started developing myopia and also when I started wearing glasses. Not only that, (I'm Asian) my grandmother was always strict about my education and I was pressured to be a straight A's student. In fact, she even made me solve advanced math problems during summer break from morning to night. At 17, I was officially diagnosed with depression and by that time, I learned that sunlight and chocolates helps stimulate dopamine. I'm 26 now and I have horrible vision, but I try to get as much sunlight as I can now.

That sun-light theory sounds plausible. I got my first glasses when I was 14. I was -1,25 diopters on both eyes. With 17 I got my second pair of glasses, I was -1,75 dioptres at that time. Now at the age of 19 I see just as bad with glasses as I did right before I got my second glasses. Between 14 and 17 I used to be outside every day for at least 5 hours. Now I stopped going outside that frequently because, well, memes. So It is actually really plausible.

Vriska Serket My question was based on the idea that people tend to spend more time outdoors when it's warm, and less when it's cold. Anyone can be an anomaly, but "more common" and "less common" myopia would depend on averages. Also, sunburn is caused by ultraviolet radiation, not heat. The warmth of the sun is felt from the infrared spectrum.
