Could bionic eye end blindness?
Artificial vision for the blind was once the stuff of science fiction -- Lt. Geordi La Forge's visor on "Star Trek" or the bionic eye of "The Six Million Dollar Man." But now, a limited form of artificial vision is a reality -- one some say is one of the greatest triumphs in medical history. "We are now at a watershed," Joseph Lazzaro, author of "Adaptive Technologies for Learning and Work Environments," told CNN. "We are at the beginning of the end of blindness with this type of technology."
