Contact lens like Google Glass

Researchers mounted a light-emitting diode directly into a contact lens, so they will diagnose disease, project images straight onto our eyeballs, like a tiny Google Glass.

A group of chemical engineer at the Ulsan National Institute of Science and Technology, led by Jang-Ung Park, mounted a light-emitting diode on an off-the-shelf soft contact lens. They developed it using a transparent, highly conductive, and stretchy mix of graphene and silver nanowires.

The researchers tested these lenses in rabbits (they have eyes similar in size to humans) and found no ill effects after 5 hours. The animals didn’t rub their eyes or grow bloodshot, and the electronics kept working.
