They have the technology, and now
scientists in the U.K. have given sight to the blind using bionic eyes.
Electronic microchips implanted into the eyes of a group of British patients
suffering from retinitis pigmentosa, an incurable genetic condition that causes
blindness, have partially restored the vision of the formerly sightless so that
they're able to view the world as a "grainy black-and-white image." The
implant's first British recipient said the bionic eye gives him "some
imagery rather than just a black world." Another patient reported suddenly dreaming in
"very vivid color for the first time in 25 years" because a part of his brain
had been reactivated.
