Light-powered bionic eye invented to help restore sight

A retinal implant – or bionic eye – which is powered by light has been invented by scientists at Stanford University in California.

Implants currently used in patients need to be powered by a battery.

The new device, described in the journal Nature Photonics, uses a special pair of glasses to beam near infrared light into the eye.

This powers the implant and sends the information which could help a patient see.

Diseases such as age-related macular degeneration and retinal pigmentosa result in the death of cells which can detect light in the eye.

Eventually this leads to blindness.
