Electronic glasses auto-focus on what you're looking at
They're not very pretty, but prototype eyeglasses from University of Utah scientists could make progressive lenses obsolete for older people. Using electronically activated lenses and infrared distance meters, they can focus automatically on whatever you're looking at, whether it's far or close up. Once perfected, the device could eliminate the need for multiple pairs of reading or driving glasses for folks with presbyopia or farsightedness.
