In Germany, the Tübingen and Regensburg universities there is a hospital carring out a study to help the blind. Eberhart Zrenner is the leader of this project. The project involves implanting chips into the eyes of seven people who have lost their sight to a disease called retinitis pigmentosa. Silicon chips to allow machines to see is commonplace so why not use them to help the blind. Chip enables blind people to gain impressions of vision

Retinitis pigmentosa no medical treatment is an inherited disorder that accounts for 11% of cases of blindness. It rods the cones that detect light in the retina of the eye. luckily it does not harm the optic nerve, which transmits electrical impulses from the retina to the brain. Feed some appropriate electrical signals to this nerve, Dr Zrenner reasoned, and the brain would be able to see again.
