“If you're one of the many who wear prescription eyeglasses with bifocal or progressive lenses, your life could soon become much simpler, thanks to a company called PixelOptics.”
“The glasses use a thin layer of liquid crystals sandwiched between two plastic layers. Electric current from a built-in rechargeable battery alters the focal power of the lens sandwich when you tilt your head or tap the frames. A 6-to-8-hour charge can run the emPower glasses for more than three days.”


This sounds like they are using similar technology to electronic paper which is pretty amazing.I would love to try these out and see how well they actually work.
