This is just cool (from Popular Mechanics):
A team at the University of Washington has created a contact lens assembled with functional circuitry and LEDs.

Potential uses include virtual displays for pilots, video-game projections and telescopic vision for soldiers. A working prototype of a lens-embedded antenna that draws power for the device from radio frequencies has also been created. The next steps are to build a version that can display several pixels—and then to test it on a person.

The UW team uses a technique called self-assembly to manufacture the eyewear. Researchers dust a specially designed contact lens with microscale components that automatically bond to predetermined receptor sites. The shape of each component dictates where it attaches.

“There’s a lot of room to expand,” Babak Parviz, an assistant professor of electrical engineering at UW, says of the technology. “You can let your imagination run wild."
