Seeing the light

A new implant inside the eye can change the life of a blind person whose retinas retain at least some functionality. How it works:

Capturing the scene

Visual data are sent to glasses

The eye implant receives data

A camera on the glasses captures a scene, and the video is processed through a small portable unit.

The video is transformed into digital instructions and is sent up to the glasses' receiver.

The digital data is then sent wirelessly to the eye implant.

An electronic array emits small pulses of electricity to stimulate the retina's still-functional cells. The pulses are perceived as patterns of light.

The visual pattern is transmitted along the optic nerve to the brain.

Users learn to interpret the visual patterns.
