" Most advances in retinal implants concentrate on restoring, not enhancing, sight. But there&amp;#039;s hope yet for superhuman vision, and without surgery: 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. &amp;quot;There&amp;#039;s a lot of room to expand,&amp;quot; Babak Parviz, an assistant professor of electrical engineering at UW, says of the technology. &amp;quot;You can let your imagination run wild.&amp;quot; "^^<http://www.w3.org/2001/XMLSchema#string>
