Restoring sight to the blind has proved particularly challenging for scientists, but a new technology combining an eye implant and video-camera-enabled glasses may soon be available in the U.S.
Researchers have been pursuing the development of such a bionic eye for decades, in some cases spending hundreds of millions of dollars to tackle engineering challenges. One device designed to help people with a rare eye condition is awaiting U.S. regulatory approval. It is known as Argus II, made by Second Sight Medical Products Inc. of Sylmar, Calif. Other researchers, including at the Massachusetts Institute of Technology and Stanford University, continue to work on what they believe are even more sophisticated versions.
Second Sight's product uses what is known as a retinal prosthesis that bypasses the dead or damaged cells in the eye needed to detect light. Instead, the device reroutes visual data via the implant to parts of the eye that still work. Like other similar devices under development, it uses a video camera embedded in a pair of eyeglasses to collect visual input in the form of light and transmit it to the implant as an electrical signal.
