Myopia, at least for children, could be the result of lack of exposure to sufficient light during the growing phase ( https://www.youtube.com/watch?v=DjdkbcOx05A ).In the research, chicks with exposure to 10000+ lux had prevented myopia, while the other chicks which didn't get exposed to enough light developed myopia. The overall recommendation from the study was for children to get at least 3 hours of outdoor activi…

In contrast to your anecdote, my brother went outside far more often than I did growing up, and his nearsightedness is both much worse and getting worse more quickly than mine (mine has changed between .25 and .5 over the last 10 years, his has changed by something like 2 in the last 5).

Knew a co-worker who'd worn glasses her whole life said her eye sight got better after she turned 50. The optometrist told her the muscles around your eye weaken and don't squeeze your eyeball as well, thus changing the focal point.

Please stop doing this. We all know anecdata isn’t, so why continue to spread the trope? “It’s not data, but...” Then don’t share it.

Everyone in my family said to me as a teen why aren't you wearing your glasses? You know your eyesight will get worse. Ten years later as a 27 year old I went to the opticians and they had got worse by .25 which my optician told me is so nelgigible that people drop by that in six months. I know this is hardly a scientific study but I do get suspicious sometimes the advice to wear glasses is coming from the opticians…
