Researchers at the University of Washington managed to embed an electronic circuit and LEDs directly into contact lenses, which seemed to look good on rabbit eyes. Though the circuit is not functional and the lights don’t light up, the development shows that future applications like direct video to the eye may indeed be possible.
The prototype contact lens does not correct the wearer’s vision, but the technique could be used on a corrective lens, Parviz said. And all the gadgetry won’t obstruct a person’s view.
“There is a large area outside of the transparent part of the eye that we can use for placing instrumentation,” Parviz said. Future improvements will add wireless communication to and from the lens. The researchers hope to power the whole system using a combination of radio-frequency power and solar cells placed on the lens, Parviz said.
