According to ScienCentral.com (March 15, 2007), the device uses an ocular implant to essentially bypass damaged retinas, which can no longer translate light into the electrical impulses the brain interprets as visual images. Here’s how it works: The camera sends images to a microprocessor (also on the glasses) that converts them into electrical impulses and wirelessly beams the impulses to the implant, which in turn sends them to the optic nerve–the highway to the brain.
An earlier version of the device, tested in 2002, helped patients perceive light and motion.
It will help patients see the outlines of obstacles like curbs and doorways. But it probably won’t restore a person’s ability to recognize faces or to read.
