“This allows folks that square measure utterly blind to check enough to boost their quality,” says Mark Humayun, a faculty member of medical specialty engineering at the University of Southern Golden State in l. a. UN agency has been developing the device for the past twenty five years. “It permits individuals to create out the walk ANd be it while not twisting an gliding joint, see surprising obstacles like position cars, decipher a table, see somebody coming back through a entranceway,” he says. Some patients will decipher giant letters, however the most perform of the implant is to grant patients enough sight to revive quality.
The device, known as the Argus II, has 3 main parts: a glasses-mounted video camera; a transportable computer; and a chip ingrained close to the membrane. The video camera sends image information to the pc, that is worn on a belt. The processor converts the image information into electrical signals that square measure beamed to a chip ingrained close to the membrane. The signals square measure then sent to AN array of sixty electrodes that stimulate the retinal cells. These electrodes basically do the work of the light-sensing cells that have degenerated. So far, the system can’t facilitate patients decipher totally different colours, however it will give them with enough sensation to sense the outlines of things close.
