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?

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.

There are limits to how much the body can heal itself from certain injuries. But your eyes getting worse is not an injury or something, its just an effect of the aging process. Certain parts of your body can just degrade over time. Many factors go into this, nutrition, geographical environment, genetics, etc. So everybody’s eyes degrade at different rates depending. Like, if you get a scratch on your eye like from dirt or debris getting in your eye, that part can heal itself over time. But again that is considered an injury, not a natural result of time.
