A Light-Powered Retina Implant For the Blind
the_newsbeagle writes: In certain diseases of the retina, people lose function in the photoreceptor cells that respond to light and trigger a message to the brain. So engineers have designed various retina implants that do the job instead, including the Argus II system, which received the first FDA approval for an implanted visual prosthetic in 2013. But the Argus II only produces vision of about 20/1200. A new implant in the pipeline from Stanford University has already achieved 20/250 vision in rats, and is aiming at 20/120, which would be below the legal threshold for blindness. This implant is photovoltaic, so the same infrared light that beams an image of the world into the implanted chip also powers its electronics.Read more of this story at Slashdot.
