Cheri Robertson is blind, but this device allows her to see, not with her eyes but with her brain. Fifteen years ago, she lost both of her eyes in a car accident. She was just 19 years old.
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.
