George,
I was thinking about what you said, I did not think the experiment would work with contact lenses. I could think too many things going wrong with it as well. I have thought of another 7 ways to test since then but like test 1 and 3 still test perception of the brain of the visual data. The one that may work though is number 2, where they intercept the signal from the eye(nerves) but before it hits the brain. Scientist could then see what detail an eye truly sees (outside the center)without having to depend on the realtime processing of the brain on a moving image.
