Maybe kids predisposed to nearsightedness aren't outside playing many sports because it's slightly harder for them to see, so they spend more time inside reading or other things that's easier for them to see closer.

My wife's son is 23 and sits about a yard from the TV screen. The only time he is outside is going to 'Rocky Horror' on Saturday nights. His vision is fine, but then neither of his parents wore glasses until their 40s.

I had an astigmatism correction since 7 and played outside year 'round, even in the winter. Didn't get a new prescription until I hit 47.

Fano: Glasses are the price society pays for literacy. That said, kids learn spatial awareness better on a bike than sitting on a couch with an iPad.

Obvious tag is correct.

There is definitely a genetic predisposition to myopia (as  cgraves67's story indicates), but environmental factors are hugely relevant too. I'm continually surprised at how much resistance there still is to the idea that what you do with your eyes will impact your vision. (That one Seinfeld opening bit about eyesight always bothered me as being ignorant).

Fact is, while predispositions are clearly there, generally, if you strain your eyes looking at close sources (books, magazines, computers, phones, etc), then your eyes will adjust toward nearsightedness--that's what biological systems do--they seek homeostasis. And if you focus on far sources (the sky, landscapes/horizons, and even just driving or walking around a construction site/battlefield/cop beat), then your eyes will adjust toward farsightedness.

CSB: I used to be myopic in middle & high school. I found an optometrist who knew that the eyes are protean, and so prescribed not corrective lenses, but adjusting/relaxing lenses--to fool my eyes into believing I was looking at things further away. He also prescribed some eye relaxation exercises and advised that I spend more time outdoors. Within two years I was became mildly farsighted, and have remained so since, with minor variations (slightly worse in college, better still since then).

Myopia is one thing, but kids not knowing what the night sky really looks like is sad.  I've never witnessed it myself, but I've heard both random and personal accounts of kids and even adults raised in the city that went to an area with little light pollution for the first time and they were terrified.

I do.  This weekend we went hiking, and as the days lengthen, they are going to be outside much more after school.

It's an interesting notion. I was one of the few kids in my elementary school with glasses (this was in the early '70s), but it seems like at least half the pre-teen kids I see these days wear them.
