An earlier post on this blog already displayed the possible future of sight using augmented contact lenses. Researchers at MIT take this second sight to a next level by creating a retinal implant that could help blind people regain much of their vision.
People receiving the implant would wear a pair of glasses with a built-in camera that wirelessly powers the implant and sends images to a micro-controller on the eye-ball. These are then processed and send to electrodes implanted below the retina.
Besides the immense value for blind people imagine the future possibilities for truly virtual and augmented reality. Always wanted infrared sight? Or would you prefer to hook it up to your Second Life account? You can also just watch a movie.
