Researchers at Second Sight developed the Argus II, a device that features a small camera attached to a pair of glasses, a portable processor that translates an image into electrical stimulation and microchip and electrodes that are implanted on the retina to help patients with visual impairments "see" and read braille patterns without touching them. The device helped a patient "read individual letters in less than a second with up to 89 percent accuracy," lead author Thomas Lauritzen wrote in a journal Frontiers of Neuroprosthetics news release.
