Brain implant restores partial vision to blind people

Medical experts hail 'paradigm shift' of implant that transmits video images directly to the visual cortex, bypassing the eye and optic nerve

Partial sight has been restored to six blind people via an implant that transmits video images directly to the brain.

Some vision was made possible - with the participants' eyes bypassed - by a video camera attached to glasses which sent footage to electrodes implanted in the visual cortex of the brain.
