Retinal Implant 'Enables Blind People To See

Researchers in Germany have developed a retinal implant that has allowed three blind people to see shapes and objects within days of the implant being installed. Impressively, one blind person was able to identify and find objects placed on a table in front of him, as well as walking around a room independently and approaching people, reading a clock face and differentiating seven shades of grey. The research is published in Proceedings of the Royal Society B.
