It is common knowledge that bionic eyes receive power from batteries. The existing technology and setup when it comes to bionic eyes dictate the use of wires and battery. However, scientists at Stanford University have invented a new subretinal implant that provides power through infra red beams and electrically stimulates neurons.

Various age related problems such as macular degeneration and retinal pigmentosa cause the death of cells which detect light in the eye. Ultimately, this leads to blindness.

In modern days, retinal implants have given the ability to some patients to see again. However, the chip that is installed behind the retina requires power from a battery that’s installed behind the ear, and wires that connect the two. The implant invented by scientists at Stanford has eliminated the need to have this complex wiring arrangement. The new setup requires the user to wear a pair of glasses that is fitted with a camera. The camera records everything and sends infrared beams to the chip behind the retina. This in turn creates electrical signals which is then passed on to the nerves, ultimately allowing the person to detect motion, perceive light, and identify basic shapes.

Since the chip is very thin, and the setup is totally wireless, the surgery required is very simple. This implant has not been tested on humans yet. However, it has been successfully tested on rats.
