Researchers from the University of Tubingen in Germany have developed a new retinal implant that allows users to see without using an external camera. Geared towards patients with retinitis pigmentosa and similar diseases that destroy light-sensing cells in the eye, the implant detects light entering the eye and sends signals directly to the brain. Users can adjust the brightness of their view using a dial located behind their ear. An almond shaped field of vision is restored to the user with the wirelessly powered device.
