One of the monsters of Greek mythology, Argus, possessed thousands of eyes. That might have given him an advantage in a fight, but he still got killed, and it is said that his eyes now exist in the feathers of peacocks..

What has always made me think is how both cameras and brains actually tweak images as they go their respective "brains". The image is often upside down, color inverted, etc. And how, for instance, I wear a prism lens in my glasses for a nystagmus (not astygmatism) in my left eye. But the prism lens is for the right eye because of the way the brain works. The adjustment necessary to stop my left eye from spasming is administered through the right eye. Brains are weird.
