Bio-electronic implant

It has come to light that researchers that are based at MIT are confident that they will be able to restore partial sight to people who have slowly gone blind because of degenerative diseases of the retina within a few years.
It’s said that the bio-electronic implant which is said to be the size of a pencil eraser, would actually sit behind the retina at the back of the eyeball, and images would be transmitted to the brain via a connector the width of a human hair.
The only thing with this is those who were blind from birth or suffer from glaucoma are unfortunately ineligible for the procedure.
What do you think of the idea?
