Inventor, Babak Parviz has invented a contact lens embeded with solar-powered leds and a radio-frequency receiver. Intially, Babak Parviz developed the contact lens to wirelessly communicate medical information about the health of the eye and wearer. However, other applications were soon realized. According to Parviz, "There are many possible uses for virtual displays. Drivers or pilots could see a vehicle's speed projected onto the windshield. Video-game companies could use the contact lenses to completely immerse players in a virtual world without restricting their range of motion. And for communications, people on the go could surf the Internet on a midair virtual display screen that only they would be able to see."
