Japan, the first artificial retina to be created that works like a mini film camera and computer

A group of Japanese researchers from the University of Osaka has made a bionic retina than can restore up to 60% of eyesight. It is still little more than a prototype, but it differs from all previous devices developed (based substantially on the use of micro-film cameras that capture and transform images into electrical impulses) because it uses an 'analogic' method: the Japanese-made high-tech retina does not in fact process the information coming from the outside world, it just performs the transmission work normally done by the retina and in effect imitates the structure and its electrical properties.

The retina is a multi-layered tissue that transforms light into nervous impulses, and the device developed by the Japanese team carries out this function thanks to the use of six microchips. The bionic retina can also be directly implanted into the eye (without the help of any other device), it consumes very little energy and, above all, it does not reach high temperatures, a fundamental characteristic for the avoidance of rejection phenomena.
