Forget sitting too close to the television, its just a matter of time before a screen can literally rest on the eyeball. Scientists at the University of Washington are working on a new breed of contact lenses with embedded LEDs which allow information to be displayed to the wearer. This human machine interface will use custom-built transparent circuitry in a polymer lens that is roughly 1.2 millimeters in diameter.
