The movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. That was an amazing special effect contact lens which is now a reality that is to come true. Off the screen, virtual displays have been proposed for more practical purposes — visual aids to help vision-impaired people, holographic driving control panels and even as a way to surf the Web on the go.

There are many possible uses for virtual displays which can be possible in days from now. Drivers or pilots could see a vehicle’s speed projected onto the windshield. Video-game companies could use the contact lenses to completely immerse players in a virtual world without restricting their range of motion. And for communications, people on the go could surf the Internet on a midair virtual display screen that only they would be able to see.

The special lens 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.This is a good thing to hear that it might have no effects also on human eyes.

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 a UW assistant professor of electrical engineering.

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.

The research for special effect lenses has been very deep that movies has become reality.  This is an amzing news since this could give people a clear view with a good special effects that can be useful for humans.
