Artificial Vision
From: Technology Review - May / June 2011 - page 20

People blinded by degenerative eye disease could have some of their sight
restored by the first commercial retinal prosthesis. A camera mounted on a
pair of glasses feeds an image to an array of 60 electrodes implanted in the
wearer's retina. Although the resulting vision is limited, it's good enough
for recognizing simple objects, finding doors and windows, and, in some
cases, even reading large print.
