Microchip may help blind people see again

摘要

A chip inside the eye that can help blind people see again is moving closer to reality as researchers at MIT work on a retinal implant that can bypass damaged cells and directly offer visual input to the brain.rnPatients who receive the implant will wear a pair of glasses that has a tiny camera attached to it. The camera will send images to a microchip implanted in the eyeball that channels the input to the brain.rnIt will not entirely restore normal vision, say the researchers, but it will offer just enough sight to help a blind person navigate a room.
