Second Sight Medical Products has developed a medical device, Argus II retinal prosthesis system, that gives blind people a form of sight.

The device includes a miniature camera that fits into the patient’s glasses, which converts video images into a series of small electrical pulses. The impulses are transmitted wirelessly to electrodes implanted on the surface of the retina. These stimulate the remaining cells in the retina to create patterns of light in the brain, and the brain learns to interpret these patterns.

This has been developed for patients who have lost their sight through retinitis pigmentosa, an inherited eye disease that damages the retina at the back of the eye.
