This article is the first I've heard of this theory:


I find it interesting because I've never been convinced by the "too much time reading" stuff. Anyone else aware of additional data for or against it?

I don't buy this either. I was always outside playing when a child and needed glasses by the time I was 13, my older brother by the time he was 10 but younger brother never needed glasses for myopia. My father began wearing glasses for myopia in his early teens. He was outdoors much of the time. Dad was born in 1923, I am approaching 60 so it was before tv, video games and other such indoor amusements.

At 46, I found that I was getting severe eyestrain from any reading. After I went paleo and began supplementing with D3/getting more sunlight, that went completely away.

Yeah I'm not sure I buy this study, maybe I'm an anomaly but I grew up in a very outdoorsy family in southern california - I find it hard to believe I wasn't getting enough sunlight and I needed glasses by the time I hit high school.

Well, every individual's habits alone like excessive reading, watching television ,etc cannot be blamed for developing short-sightedness.It could be the lack of proper nutrition, essential minerals, vitamins and proteins in your diet and also the kind of genes that is passed on to you.If your family history points that many of your ancestors and your parents had poor vision,then the incidence of you developing short-sightedness would be very high.Thus, I think it is wise to ensure a healthy and wholesome diet and not the "glorified urban junk" to your kids while they are growing up.It is also essential to involve them in healthy physical activities and regular exercise.Yoga, deep breathing and meditation would also help wading away some weaknesses that kids are likely to develop during their growing years.
