Circuit Smart Contact Lens, Presaged By Niven, Barnes and Vinge
Contact lenses with imprinted electronic circuits and lights for augmented reality display vision are under development by University of Washington scientists.

The UW engineers used microscopic scale manufacturing techniques to create a flexible, biologically safe contact lens with imprinted electronic circuits and lights. If used by human beings, a pair of contact lenses with circuits and lights would be the perfect display for augmented reality systems.

The prototype device contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up. The lenses were tested on rabbits for up to 20 minutes and the animals showed no adverse effects.
"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," said Babak Parviz, a UW assistant professor of electrical engineering. "This is a very small step toward that goal, but I think it's extremely promising."
Researchers built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes one third of a millimeter across. The researchers hope to power the whole system using a combination of radio-frequency power and solar cells placed on the lens.
Science fiction readers are fortunate to have had this idea presented to them several years ago. In his 2001 novella Fast Times at Fairmont High, sf writer, computer scientist and mathematician Vernor Vinge described a near-future world in which everyone used smart contact lens displays. In his 2006 novel Rainbows End, set in the same milieu, he describes them this way:
Miri... leaned her head forward, and stuck a finger close to her right eye. "You already know about contacts, right? Wanna see one?" Her hand came away from her eye. A tiny disk sat on the tip of her middle finger. It was the size and shape of the contact lenses he had known. He hadn't expected more, but... he bent closed and looked. After a moment, he realized that it was not quite a clear lens. Speckles of colored brightness swirled and gathered in it. "I'm driving it at safety max, or you wouldn't see the lights." The tiny lens became hazy, then frosty white. "Uk. It powered down. But you get the idea.."

The results were presented today at the Institute of Electrical and Electronics Engineers' international conference on Micro Electro Mechanical Systems by Harvey Ho, a former graduate student of Parviz's now working at Sandia National Laboratories in Livermore, Calif. Other co-authors are Ehsan Saeedi and Samuel Kim in the UW's electrical engineering department and Tueng Shen in the UW Medical Center's ophthalmology department.
A full-fledged display won't be available for a while, but a version that has a basic display with just a few pixels could be operational "fairly quickly," according to Parviz.
Update 21-Jan-08: According to Babak Parviz, he and his colleagues got started on this idea in 2004; he hadn't heard about the Vinge story. End update.
I wrote Vernor Vinge and asked him whether or not he was familiar with Parviz' research. He replied that he was not. I asked him how he thought of the idea:
"I think I had these in "Fast Times at Fairmont High" (2001).
Basically I wanted an augmented reality display that wouldn't involve
implants but which would not appear intrusive.
The full-bore invention will be a real challenge: the form factor,
the power supply, the transparency management, the wireless
networking, the very accurate overlay positioning.
However, lightweight head-up displays will probably take off
incrementally (and soon!) and that process should be very fun to track."
I corrected the article and the reference to reflect the earlier time. Note that Vinge also mentioned "I bet there is prior sf'nal art on this!"
Thanks to diligent and alert readers, I can add to (keep correcting!) the story. In their 1992 collaboration The California Voodoo Game, Larry Niven and Steven Barnes wrote about scleral contact lenses:
To Nigel Bishop, the walls had become blue glass. He saw and evaluated holographic projection equipment, fiber optics, electrical and plumbing, communications...
His eyes no longer resembled human eyes...
"Scleral lenses?" she asked. "You've got DreamTime technology in contact lenses? That's not available to the public!"

It seems clear that the scleral contacts describe a display upon which images or data can be viewed, and the images do not appear to be projected from elsewhere upon the surface of the lens.
