I have had poor vision since birth. According to my eye doctor, my left eye is "legally blind." The left eye also tends to read less color than the right eye. My right eye does all the work, but I must wear glasses to read or paint.
Since one eye doesn't work very well, I have been told that I do not have good depth perception...but I am a good driver.
I have a friend who has a similar problem. She is a wonderful artist and you'd never know that there was anything wrong with her eyes from viewing her work. She thinks we have a design advantage because we don't get confused by depth.
I also remember having a similar discussion with a couple of (essentially one-eyed) classmates long ago in art school.
I am so often amazed at how easily (I think) I see so darn many things with one poor eye that many can't see with two good ones....go figure....
I think that you could be on to something here Marta
