Some researchers at MIT are currently hard at work on a microchip that will attach to the outside of an eye to restore sight, and they're looking to use it on humans within three years. Whoa.
The titanium-encased chip is designed to withstand staying in the human body for 10 years, and it's powered wirelessly via a pair of glasses with a power source inside. It won't bring blind people's vision up to 20:20, but it should allow them to make their way around and recognize faces, which is certainly a big step forward for the visually impaired.
