Maybe 20 years ago now, I went to an ophthamologist who was amazed at the difference between the lenses of my glasses. Seems I had amblyopia when I was young, before they realized how simple it was to cure, and so my left eye was very, very much weaker than my right.

He said that he could give me a prescription similar to what I had, one which brought the left eye up to where it would work with the right and wouldn't cause problems with my brain integrating the images. Or...he could give me a prescription that would bring my vision as close to 20/20 as possible, but I might have significant trouble with image integration.

I said, Hell, let's try it. We did.

I had a couple of days of odd things, but my vision (with glasses) is damned near 20/20. Every ophthamologist since has been amazed at my vision correction and the lack of problems I've had.

Now I keep wanting to try to cure the old amblyopia, but I keep getting told that I'm way, way, too old.

Anyway, try it. All you can do is fail. Then try it again, because you might win the second time.
