Babak Parviz wears contact lenses. But he's not yet using the new contact lenses he's made in his Seattle laboratory. Containing electronic circuits, they look like something from a science fiction movie. He's now going to add some extremely small light emitting diodes (LEDs), helping turn his prototype contact lenses into a sophisticated personal display - the tiniest one possible.

As an assistant professor of electrical engineering at the University of Washington, Parviz works on bio-nanotechnology, self-assembly, nanofabrication and micro-electro mechanical systems. He makes tiny but functional electronic devices and, using nanotechnology and microfabrication techniques, integrates them on to polymers or glass using a process known as self-assembly.

So how did he think of making a "bionic" contact lens? "Imagine a person with that kind of research expertise and background," says Parviz. "Imagine also the same person waking up every morning and putting a contact lens in his eye."

hahaha weird --- it amuses me when an idea i had about 8 years ago and included in a SF story i've vaguely been working on turns up in the real world
plus it pleases me to anticipate the focusing problem and a virtual image focused some distance from the eye 8-)
