Liquid Crystal Glasses Go Nationally Later This Year

There's a cute NYTimes post about the new electronic spectacles, called emPower, that PixelOptics unveiled recently. As you may remember the liquid crystal lens varies its thickness on the wearer's command, enabling him/her to have reading or distance glasses on demand. The article reports that “to call up reading power..., users touch the side of the frame. Batteries in the frame send along a current that changes the orientation of molecules in the crystals....The glasses... will be on the market this spring — first in Virginia and North Carolina, and later in the year nationally, said Dr. Ronald Blum, an optometrist and the company’s president. The estimated price, $1,000 to $1,200, will include frames, lenses, coatings and charger.”
