Six blind people regain partial sight thanks to ‘Bionic eye’ implant

‘Six blind patients have had their sight partially restored by a “bionic eye” surgically implanted on to their retina. Although it restores only very rudimentary vision, the device has proved so successful that its developers are about to begin a study of a more sophisticated version with between 50 and 75 patients.

If this trial goes to plan the device could be available to patients in two years, and one day it could be used to digitally enhance human sight. The bionic eye works by converting images from a tiny camera mounted on a pair of glasses into a grid of 16 electrical signals that transmit directly to the nerve endings in the retina.’
