Retinal implants may soon restore lost vision

The MIT fix is an artificial retina consisting of a small plate of electrodes, 1.2 millimeters wide, that's implanted in the eye. The person with the implants wears a pair of glasses linked to a video camera. A processor translates the visual information into radio signals, which are sent to a chip attached to the white of the eye. This chip communicates wirelessly with the retinal electrodes inside, and commands them to fire current pulses. Everything is powered by a battery pack at the belt of the carrier."
