Artificial Eyes?

From 60-second science:

When vision fails, it's often the result of damage to the eye caused by an injury or degenerative disease. In an attempt to restore such vision loss, researchers for more than a decade have been working to develop an optical prosthetic that can restore sight by delivering images directly to the brain. And it appears they succeeded. The BBC reports that a 73-year-old man identified only as Ron, who received an optical implant at Moorefields Eye Center in London last summer, can see again for the first time in 30 years.

Apparently the device works by using a tiny camera and video processor mounted on a pair of eyeglasses:

After the video processor converts the images to an electronic signal, a transmitter on the glasses sends that information wirelessly to a receiver attached to the surface of the eye. From there, the information is sent through a tiny cable to an electrode array implanted in the retina, stimulating it to emit electrical pulses. These pulses trigger signals in the retina that travel through the optic nerve to the brain, which perceives patterns of light and dark spots that correspond to the electrodes stimulated.

Other tests have shown promise for the prosthetic eye, with 11 of 17 reporting some degree of restored vision.
