Qube:
I'm still skeptical.
This wikipedia page discusses the subject. Seems the jury is still out on whether near work will cause myopia:

That page says one theory is that your eye lens muscles weaken, but that this is not borne out because your eye muscles actually need to release to focus on near objects.
But others say that the eye's lens gets stuck in the near position. The page does not say this has been disproven, and it seems perfectly logical that if you have a lens that needs to be stretchy to focus at a distance and you leave it in one position for a long period of time, that it might become less elastic and get stuck in one position.
I wonder if one could use an electrical stimulator to exercise the lens during sleep and bring back some of the stretchiness. You may not be able to exercise it on your own, because once you can't focus at a certain distance, you may not be able to make the muscles contract further.
Hmm... I wonder if rapid eye movement during sleep might be designed to help prevent the lens from getting stuck in this way?
Anyway, this page links to a recent study which says that students eyes get worse during months which they study, and stop getting worse during months when they are on vacation. This seems to me to be strong evidence that focusing on books and computer screens is in fact contributing to Myopia.
