In Elche Spain, there’s a neuroengineer named Eduardo Fernandez who has a lofty goal: to bring vision back to the 36 million blind people around the world. A recent MIT Technology Review article discussed his method, which involves glasses outfitted with cameras and a jack that go directly to the brain. Earlier solutions to blindness focused on creating an artificial eye or retina, which only worked for people who didn't have damage to the nerve system that connects the retina to the back of the brain.
