Science is incredible. There is now a device that helps blind people see- through their TONGUE!!!!!
The idea behind it all is your brain is actually the organ that sees rather than your eyes. The brain interprets and organizes the information sent by the eyes. Scientists found a way to bypass the eyes- through the tongue. Small cameras strapped on the forehead convert images to a grey scale image and send an electrical impulse to the tongue. The brain interprets the impulses and a blind man can see. Hopes are within a few years the device will be wireless. The mouthpiece will fit on the roof of the mouth and the camera inside of a pair of glasses.
