If you've ever wanted to be the Bionic Woman or a Terminator, new research may at least let you see with their eyes. Scientists have taken the first step toward creating digital contact lenses that can zoom in on distant objects and display useful facts. For the first time, engineers have installed an electronic circuit and lights on a regular contact lens. The prototype they created does not actually light up or display information. But it proves that it is possible to build an...

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. 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. The device to make this happen may be familiar. Engineers at the University of Washington have for the first...

NASA -- Imagine waking up in the morning to find that your vision improved overnight as you slept. While it may sound like science fiction, the technology is here today thanks to some out-of-this-world research.This advance got its start in 1993 when NASA joined forces with Paragon Vision Sciences Inc. of Mesa, Ariz., to study the production of plastic in the weightlessness of space. Free from the effects of gravity, scientists hoped their experiments would lead to a process that could...

A magnifying glass is a convex lens, usually mounted in a frame with a handle, which is used to produce a magnified image of an object. The glass works by creating a magnified virtual image of an object behind the lens. However, the distance between the lens and the object must be shorter than the focal length for the glass to work. If the distance is not correct then the image will appear small and inverted. Many magnifying glasses are mounted on a stand to insure the proper distance...
