Myopia examined

Quote:Researchers are unsure why time outdoors helps prevent the onset of myopia. "One idea is that it's just the amount of light to which children are exposed," said Jeffrey J. Walline, O.D., Ph.D., associate dean for research, also at The Ohio State University College of Optometry. "In theory, more light causes more dopamine release in the retina, which slows eye growth." Curiously, once myopia has begun to develop, spending time outdoors does not appear to slow its progression, he noted.


An irreversible trend, thanks to gaming and helicopter parental paranoia driving them to keep kids off the street. Contemporary companion of super-cleanliness germ elimination undermining immunity. No surprise that super-geek E & SE Asia are suffering the most from it (they have send to some of those kids to special boot camps to wean them away from tech and engage in more physical activity).

lol u posted that in a hurry.

vitamin deficiency in food matched with escalating food price inflation might have something to do with it.
electro magnetic radiation around pregnancy ?
excessive carbohydrate consumption during pregnancy ?
obesity during pregnancy ?

obese pregnancy is a relatively new breeding issue for the species.
one that is probably too hot to touch for most media & and consumer driven company branding issues.

its far easier to blame parental political dispositions as a cause instead of diet & personal health management, or the cost of living for the mode working class family.


drinking furodated & chlorinated  water while pregnant ?

Not at all. The quote concerned spending time outdoors. Blame the researchers if you don't like them focusing on that rather than _X_ pet peeves or _Z_ conspiracies. Or wait another 20 years when the study community may reverse gears and be trumpeting that as myth and something else as a preventive. If you don't currently like an item in the biomedical and the psycho-social sciences, then just wait and it'll change.

Quote:The best prevention for myopia in children is more time outdoors. Taiwan is making outdoor time part of the school curriculum, an initiative led by Pei-Chang Wu, M.D., Ph.D., director of the department of ophthalmology in the Kaohsiung Chang Gung Memorial Hospital. Since they increased time outdoors to a couple of hours in 2010, children's vision is improving. Delaying the onset of myopia may reduce the severity of myopia and translate into proportionate reductions in high myopia, Morgan said.

My experience seems to fit almost perfectly with the scenario laid out in the article.  My trouble with seeing began at a young age and the progression continued on and on well past the point of legal blindness.  I lived about the first four years of my life almost solely indoors as far as I can recall.
