Here's another partly related comment:
I have diplopia, double-vision. When I first got hit with it about 9 or 10 years ago, while I was waiting for the lab to make my lenses so I could go out in the world again, I would sit in my Barcalounger about 20 feet away from my TV at home, and try to watch the screen.
Now try to imagine seeing two different screens, one with your left eye, the other with your right eye. They are offset enough from one another that you can see two complete screens, side-by-side.
OK, now here's the interesting thing: Since I am trained to notice subtle differences in video screens, I found myself seeing these two side-by-side images of the same screen, and one looks more green than the other, while the other looks more red than the one.
From what my optometrist told me, most people have the same color perception difference between one eye and the other. I'd love to set up a controlled test of this for high-level colorists to see if their eyes have similar perception differences.
Well, I thought it was interesting.
EDIT: This is not an easy thing to do, compare the vision from one eye with that from the other. You have to use your mind to consciously swap your dominant eye without losing the perception of both screens at the same time. It's very tricky.
