[Harry Potter] Why didn't anyone fix Harry's eyesight?

He magically regrew his bones and came back to life. Even us muggles have contacts and lasers.

You'll note that other wizards have glasses, including Dumbledore. You'll also note they can't regrow eyes - Moody had to have an enchanted one.

It's possible eyes are one of those things that is too difficult to magic.
