Preventing myopia?

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.

No,it's not true that close work leads to myopia.myopia is due to developmental abnormality of the eye that more or less depends on genetics.There's till now no proved way to prevent myopia.

Yes, and the environment also helps. brighter places are good for reading.

Yeah, ive read that site... I have a real issue with the amount of fear mongering they spew out claiming everybody will get retinal detachment which is a bunch of garbage...

yes retinal detachment does exist and yes people with higher rates of myopia have a higher chance of getting it but the percentage of people even with high myopia that get retinal detachment is VERY LOW and should not be the base for their argument...

extensive close-up work however has been considered as something that progresses myopia, that is ALONG with genetics but this is still a relatively new field...

I mean if you took a look at that amount of people wearing glasses in a university compared to those that grew up on a farm the results are pretty staggering...

the point is the environment and doing work close-up likely DOES play a role for SOME but look at all the people that do a LOT of close-up work and still have 20/20 vision... as long as you take regular breaks and look into the distance every so often you should be okay....

What are you going to do, stop reading and using your computer?

hope this helps, if your still concerned talk to some eyecare experts... good luck :)
