Liquid-crystal glasses

Juniper Foo | May 09, 2006

Here's the long and the short of it. Thanks to a team of researchers in Arizona, it's bye bye soon to headache-causing bifocals, which are essentially two lenses in one that are so often disorienting to use. What lies ahead are liquid-crystal eyeglasses that can automatically change focus depending on the line of sight of the wearer. In scientific terms, a layer of liquid crystal is sandwiched between two layers of glass containing a circular array of transparent electrodes. The electrodes are activated by an electrical field that causes the liquid crystal to reorient within less than a second into rings, focusing light to pass through the lens in a certain way. If being four-eyed ain't your thing, there's always Lasik for the vain pots.
