Bionic eyes that return sight to the blind might not be as far off as previously thought, with researchers in London carrying out the first treatment on a pair of patients in a study of a new technology.
The new bionic eyes are connected to a camera on a pair of glasses, so they aren't the all-in-one models you're envisioning. And if successful, they'll really only allow patients to see light and dark outlines rather than full sight. But still, to someone who has no vision at all, this is still pretty great news. And if they're working on it in this state now, you know that they'll have the camera in the eye itself and the vision improved as the years go on. [BBC]
