According to the World Health Organization, 285 million people worldwide are visually impaired. Thirty-nine million are blind, while 246 million have low vision.
In addition to glasses and contact lenses, there are other prosthetics that can be implanted in the eye to improve vision.
Bradley Greger, an associate professor at ASU, is partnering with a California-based company called Second Sight on technology that can be placed on the retina to provide a limited amount of vision to blind people.
But he’s also working on a method to put something directly in the brain to help eyesight. He’s with me to talk about it.
