Computer Display Contact Lens Could Put Data On Eyes

The opportunity to jab yourself in the eye with a tiny computer display is one step closer, thanks to the ongoing work with opto-electronic contact lenses taking place at the University of Washington in Seattle. The lab there has been showing off the latest prototype, the handiwork of Dr. Babak Parviz: a semi-transparent array - including an LED - embedded into a contact lens that receives 330 microwatts of power wirelessly from a nearby RF transmitter. Parviz has been using the prototypes to display biosensor feedback about the wearer's vital signs, but they'll eventually serve as a heads-up display for displaying other data.
