Bionic Eye Implant

 Created by a team of researchers at MIT, the bionic eye featured above is an early prototype designed to help restore partial sight to patients who have suffered vision loss due to retinitis pigmentosa or age-related macular degeneration, the two most common causes of vision loss.

Worn as a part of a system, the eye would be surgically implanted into the patient with the electrical nodes sitting just under the retina and in contact with the optic nerve. These nodes would be fired when an image is transmitted to the implant by means of a camera embedded in a pair of glasses that the user would wear, and this stimulation of the optic nerve would transmit signals to the brain which mimicked partial vision and would allow the user to regain partial vision in the damaged eye . While not a restoration of full vision, the implant is a first step towards technologies which would facilitate full vision restoration for those affected by vision loss.
