The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight.
A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness.
They are usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid 1980s.
Argus II, manufactured by Second Sight Medical Products Inc. is the only such device to have received marketing approval by the United States FDA on 14 February 2013, as the first Artificial Retina technology.
Argus II is the first approved prosthesis to restore limited vision to those blinded by retinitis pigmentosa. The prosthetic technology was developed at Second Sight, USC, UCSC, CalTech, and other research labs, with support from three major US government funding agencies (National Eye Institute, Department of Energy, and National Science Foundation - NSF).
The Argus II is manufactured by, and will be distributed by, Second Sight Medical Products of Sylmar, California later this year. Check out the video!
