My eye problems were ignored till I was way past the age when anything could be done about them. I was doing well in school, so nothing could be wrong - that was my parent's attitude. They were wrong.
I think the best thing that happened to my weak eye was wearing contact lenses for many years. They do a better job than glasses, and when my weak eye started seeing better, my brain begin to pay more attention to what it was reporting. It was biofeedback, I believe.
With good glasses I see pretty well. I also amaze my friends by taking my glasses off and seeing remarkably tiny things with my weak eye.
One effect of the problem is that I'm left-handed. I write with my hand curved towards me, and the books say that that is the mark of a person whose brain is right-handed but who writes with the left. I think that anybody who writes like that should be allowed to do it. The brain knows what it needs.
