I was looking at this site:
nearsightedness.org

It basically says that close up work, like reading in school, along with the myopia gene causes myopia. And, we should give each child reading glasses when they read so as to avoid nearsightedness. But, it also says that glasses are given instead because eye doctors are greedy and so are the eye doctors. And, by giving children glasses, it destroys their eyesight.
I was just wondering if anyone knows how true it is that reading and doing things up close really strain your eyes so much that it causes your vision to go.
