Artificial Retina

From the NY Times:
The Food and Drug Administration on Thursday approved the first treatment to give limited vision to people who are blind, involving a technology called the “artificial retina.”

With it, people with certain types of blindness can detect crosswalks on the street, burners on a stove, the presence of people or cars, and sometimes even oversized numbers or letters.

The artificial retina is a sheet of electrodes surgically implanted in the eye. The patient is also outfitted with a pair of glasses with an attached camera and a portable video processor. These elements together allow visual signals to bypass the damaged portion of the retina and be transmitted to the brain.
