We have discovered nearsightedness is caused by a lack of sunshine during childhood. The amount of bright light you're exposed to determines when your eyeballs stop growing/adjusting and if you don't get enough you end up near-sighted.

That's a factor sometimes, but plenty of people are just genetically nearsighted.
