This engineering eye is not as perfect as the original eye. But by replacing the function of retinal cells, this bionic robot can help provide the basis for the vision of those who suffer from retinitis pigmentation or age-related muscular degeneration, the leading cause of blindness.

In addition, users will be wearing special glasses equipped with a small camera that can send images to a chip relay wrapped in titanium that is placed on the outer surface of the eyeball. The chip will then send the electrode under the retina to stimulate the optic nerve. Glasses will also wireless send that surrounds the eyeball.

MIT scientists have been working to develop this retinal implants for 20 years as part of the Boston Retinal Implant Project. Around 10 years ago, the researchers tested six electrodes in the blind patients, who reported seeing clouds like images when stimulated.

“We need three years to test this retinal implant, in order to work optimally,” explained chairman of the MIT scientists Jhon Wyatt, told Cnet.

Retinal implant has been successfully tested in pigs for 10 months without damaging the electronics.

Around 20 teams around the world who work to make dreams eye implants, is now developing cochlear implants are intended for hearing-impaired people.
