One really interesting item at CES 2011 is the new line of eyeglasses released by PixelOptics called emPower. What differentiates them from any other eyeglasses is that these are the world’s first “electronic corrective eyeglasses”. What does that mean?
Hidden in the frames of the otherwise normal-looking glasses, are a microchip, micro-accelerometer and miniature batteries. Each lens has a transparent LCD layer that can electronically adjust itself, changing the focus when necessary. If you tilt your head down to read a book or look at something up close, the accelerometer automatically detects the motion, sending a signal to the LCD that alters how light is refracted, and changes the prescription to clear the image.
