Cheri Robertson lost both her eyes — years ago — in a bad car accident, but now thanks to special electrodes implanted in her brain, she has regained partial vision. Video after the jump.
A camera on the tip of Robertson’s glasses sends signals to a computer that’s strapped around her waist. The computer then stimulates electrodes in the brain through a cord that attaches to the head. Patients see flashes of light and outlines of objects.
