Britain Artificial Retina

In this photo taken Saturday, Feb. 12, 2011, Eric Selby poses for a photograph with a “sight” camera fitted in a pair of glasses, as well as its associated computer and transmitter, which work in conjunction with an artificial retina implant called the Argus II fitted in his right eye, enabling him to detect light, in Coventry, England. For two decades, Eric Selby, 68, had been completely blind and dependent on a guide dog to get around. But after having an artificial retina put into his right eye, he can detect ordinary things like the curb and pavement when he’s walking outside. (AP Photo/Martin Cleaver)
