The new devices work by implanting an array of tiny electrodes into the back of the retina.
A camera is used to capture pictures, and a processing unit, about the size of a small handheld computer and worn on a belt, converts the visual information into electrical signals.
These are then sent back to the glasses and wirelessly on to a receiver just under the surface of the front of the eye, which in turn feeds them to the electrodes at the rear. posted by Sydney on
