In 2013, a chip was implanted into the retina of someone without sight in order to substitute/augment image processing. While the initial chip provided somewhat low resolution images, a next generation chip will allow the viewer to read large print and recognize human faces.
"We anticipate that this retinal implant will provide users with increased mobility and independence," said Anthony Burkitt, BVA's research director and an engineering professor at the University of Melbourne.

It seems another Star Trek sci-fi technology is coming to real life. Remember Geordi LaForge's visor? The new bionic retina implant is even better and you can get it right here on Earth. Go science!
