High Tech Contacts

Researchers @ the University of Washington have reported a system that would generate graphic displays directly to eyes.

Illinois ABC affiliate WHOI-TV reported that researchers "are trying to find ways to incorporate complex technology into" contact lenses. One "device under development, referred to as a 'bionic lens,' or 'e-lens,' integrates a miniature electronic circuit and LED lights between layers of polyethylene terephthalate. It's powered through radiofrequency energy transmitted to an antennae incorporated into the lens." This would allow "[c]omputer images [to] be sent to the circuit, enabling the wearer to see virtual displays." It would also allow "a wearer to play games, or surf the" Internet, "without the need for a display monitor."

The prototype contact lens - which will eventually contain LEDs - has yet to be powered up. That key step, says Parviz, is several months off. "We're looking at two different ways to transmit power. One is radio frequency power transmission. We need antennae on these contact lenses anyway because we need to transmit data to them. The other way we're looking at right now is to incorporate photovoltaic [solar] cells."
