night blindness<\/a>. The disease is hereditary in 60% of cases. There are 1,5 million people worldwide who suffer from retinitis pigmentosa.<\/p>\nHester is the seventh patient to receive a\u00a0bionic eye implant\u00a0Argus II Retinal Prosthesis Device<\/em><\/strong>, developed by\u00a0Second Sight Medical Products<\/em>, together with North Carolina\u2019s Duke University Eye Center.<\/p>\nThe bionic vision technology is based on the transmission of signals to the nerves of the blind person\u2019s retina. A\u00a0tiny camera<\/strong>\u00a0embedded in a pair of glasses detects the light and transmits it to a\u00a0miniature computer<\/strong>, which converts it into electrical signals corresponding to the synthesized image. A\u00a0wireless implant<\/strong>\u00a0consisting of 60 electrodes stimulates the optic nerve directly and thus transmits the signals to the brain.<\/p>\nHowever,\u00a0bionic vision is more limited<\/strong>\u00a0– in fact, a person can only distinguish between the light and the dark. Yet, the developers promise to expand the capabilities of the new device in the future.<\/p>\n\u201cIt\u2019s a fairly limited device, but it\u2019s an amazing leap forward<\/em>,\u201d\u00a0says\u00a0retinal expert Dr. Colin McCannel. \u201cIt\u2019s not the vision you or I am used to. But for someone who has been in complete darkness, it must be amazing to see again. I think it\u2019s absolutely phenomenal.<\/em>\u201d<\/p>\nDespite the fact that the device is not yet able to produce complex visual patterns and allows Larry Hester only to\u00a0see flashes of light and distinguish some objects from others<\/strong>, it is a true miracle for him and his family. \u201cIt\u2019s so basic<\/em>,\u201d he says in the video. \u201cThe light is so basic and probably wouldn\u2019t have significance to anybody else. But to me, it\u2019s meaning I can see light. And we can go from here<\/em>.\u201d<\/p>\n

There\u2019s a new invention that can restore sight even to those who have been blind for decades. Larry Hester\u00a0from North Carolina was one of the first patients to receive the new technology, which gave him a chance to see again, after 33 years of blindness.
