Optical Anomalies

A legendary one-eyed giant, the figure of the Cyclops appears in myths throughout the world. But a man living in a Mississippi backwoods community may have been the first truly one-eyed human being. His single orb, completely normal in every regard, was located in the center of the forehead, according to the Boston Medical Journal. And for years, sideshow and circus promoters refused to become a public spectacle.

The Mississippi man, of course, isn't the only person in the world to have ever endured an anomalous collection of eyes. There was an English foureyed man, for example, who could open and clese each eye independently and look in four different directions at once.
