World’s First Bionic Eye Receives FDA Approval 
http://goo.gl/SQ36e 
The new retinal prosthesis, called Argus II, can restore partial sight to people blinded by a degenerative eye disease. The Argus II works by substituting a small array of electrodes for the light-sensing cells that normally react to light by sending an electric signal toward the back of the retina. Those signals are relayed to the optic nerve behind the eye, and travel back along the nerve to the brain. In people with the genetic disease Retinitis pigmentosa, which affects about 100,000 people in the U.S. today, those light-sensing cells gradually stop working, resulting in total blindness. In addition to the electrode array, which is implanted in the retina at the back of the eye, the Argus II system consists of a small video camera attached to a pair of eyeglasses and a visual processor the user carries around their waist. Data from the video camera is sent to the visual processor and then back to the glasses, where it is transmitted wirelessly to the embedded electrodes.
