Photos by Alfred Eisenstaedt of a 1950 vision experiment.

Caption #3: "Graduate student Fred Snyder falling down after removing special eyeglasses that reverse and invert everything he sees. Immediately before removing glasses he rode a bicycle with perfect control along sidewlk in Central Park at end of 30 day experiment to learn whether vision is a natural function or a process that must be learned."
