Vuzix Corporation, an information technology firm based in Rochester, New York, is launching a more advanced version of its consumer video eyewear, equipped with a virtual Wrap 310 screen that enables the wearer to watch films and videos anywhere, anytime, in its integrated video system. Replacing a big box and other portable video systems developed since 1992, the new $249.95 model resembles a regular pair of sunglasses more than its predecessors and connects with mobile DVDs and iPhones, PCs and iPods. It can be fitted with corrective lenses and it runs with an AA battery that lasts 11 hours. Vuzix Corporation, which is also involved in low-vision, medical and military applications, is run by its owner, Paul Travers. It employs 55 people and turns over $20 million a year.
