> I now can see quite well without glasses which I could not do 15+ years ago. This happened to me at 40. The eye doctor explained that human eyes get thicker and more leathery as we age, which changes their shape. So if you're myopic before this time, you have a decent chance of having improved vision. It eventually goes the other way, though, and reading glasses or bifocals are needed to correct your vision.
