I'm sure glad I didn't get this. I wore glasses for years and hated them, until I read about vision therapy. My vision has definitely gotten better, without any lenses or surgery, for free (well ok, I bought a book about it), and I'm sure it could be even better if I wasn't lazy about it.
It makes sense to me, how could humans naturally get such bad vision, when it can be so disadvantageous in an evolutionary sense? Environmental factors (such as staring at a computer screen...) would seem an obvious cause, and the evidence seems to confirm it.
