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.
