Port Richey, Fla. - NextGen introduced a pair of 3D glasses that it said works with virtually any brand of 3DTV that uses active technology.

The Active glasses ($79.95 suggested retail) can reportedly be charged with a standard USB cable. Bob Dolatowski, NextGen's president, said a three-hour charge lasts about 50 hours.

They only work with active-shutter 3D technology, a spokesman told TWICE.  

Shipping is scheduled to begin Aug. 1. A case and lens cleaner are also included.
