What exactly is that vision problem that you were describing with the brain? It sounds like a learning disability.

I had it explained to be by an FAA flight physician almost two years ago. Best I can remember, he said something about the way the brain assembles images from our eyes into a single picture in the brain. As we age, that ability deteriorates, plus some people are more prone to the problem. IIRC, depth perception is also affected.

If you have concerns, you might want to see what you can find on the net and maybe even talk to your physician about it. There is a really simple eye test for finding out how much your vision is affected by it. We all have some decree of it - most never know it.
