Sunglasses could one day give virtual sight back to those with impaired-vision, that"s the idea behind the 'bionic eye" shades.

Bionic Vision Australia has introduce a sunglasses prototype for a bionic eye, which researchers hope to implant in its first recipient by 2013.

The prototype uses a tiny video camera attached to the middle of a pair of sunglasses. The camera captures images of the patients eye to the transmitter attached in the shirt pocket or on a belt.

The signal is then sent using radio waves to a microchip implanted in a patient's retina. Electrodes on the retina are then stimulated, which the brain interprets as an image.

This technology has impressed many scientists and no doubt is a mind blowing discovery, "It's amazing technology," said Leighton Boyd, who has lost nearly all his vision as a sufferer of retinitis pigmentosa.
