Why can’t eyesight fix itself? Bones can mend, blood vessels can repair after a bruise…what’s so special about lenses that they can only get worse?

Question

How is it possible to have bad eyesight at 21 for example, if the body is at one of its most effective years, health wise? How can the lens become out of focus so fast?

Edit: Hoooooly moly that’s a lot of stuff after I went to sleep. Much thanks y’all for the great answers.

Answer 1

I wish scarring could be corrected. I have scarring on my central line of vision causing me to go blind.. Nothing I can do about it except hope I don’t go completely blind!
