Solar Powered Bionic Eye To Restore Vision

Scientists at Stanford University (California) have developed a bionic eye or retinal implant powered by light vs the usually used batteries. The unique pair of wireless spectacles shafts light directly into the eye and sends signals to the implant enabling a patient to see. A video camera passing a beam of light on the retinal chip creates electric signals transferred to the nerves of the eye help in generating vision for the blind.
