Artificial Retina

Kathy Blake is blind but two years ago she got a glimmer of hope. She heard about an artificial retina being developed by a company called Second Sight and the Doheny Eye Institute in Los Angeles.  It was experimental, but Kathy was the perfect candidate.  With funding from the National Science Foundation, a camera is built into a pair of glasses, sending radio signals to a tiny chip in the back of the retina.  The chip, small enough to fit on a finger tip, is implanted surgically and stimulates nerves that lead to the vision center of the brain.
