Speaking about human vision, this is what our eyes see.



The human brain corrects what are eyes see by doing a "180" with everything we see when our eyes are open. Human Vision is like a Camera. It has two parts: the lens and the "brains." Both work together to give us normal sight.

I remember back in Public School watching a film about an experiment. A man put on a set of special "glasses" (they looked like Night Vision Glasses) which switched this view by 180 degrees. Initially - everything he saw was upside down. But after a few days, the brain corrected this and he saw normally. They shot footage of him riding a motorcycle wearing the glasses. Of course when he removed the glasses, everything went upside again and he had to wait for his brain to correct it a second time. Circa 1959.
