Interesting Fact - Blindness

A newly invented electronic chip can help some blind people to detect objects.

(Developed by Professor Eberhart Zrenner, of Germany's University of Tuebingen, and a private company Retina Implant AG, the electronic chip was embedded in the central macular area behind the retina, and while not everyone benefited, one man, Miikka Terho, 46, from Finland, who suffers from an inherited form of blindness, was able to identify letters and a clock face. It's brilliant!)
