'Braille' CL Helps People 'See'

"Much in the way Braille allows people who are blind to “see” the written word, a bionic contact lens invented by Israeli researcher Prof. Zeev Zalevsky “presses” images onto the surface of the eye to help the brain decipher through touch what the wearer is looking at," reports Israel 21c. "The lens, still in a prototype stage, uses electrical signals sent to it from a small transponder, clipped to a pair of glasses or downloaded to a smartphone. A regular off-the-shelf camera, like the one inside a phone, “looks” at a crosswalk, items for sale in the grocery store, or at a loved one’s face, and transmits the encoded image via the lens to the wearer’s cornea. The image gets translated into a tactile sensation that can be interpreted visually." Read more.
