ViewSonic also wants in on the 3D game with their pair of 3D glasses known as the PGD-150. The company already has a range of 3D projectors for the masses, relying on the NVIDIA GeForce 3D Vision system in order to create the 3D effect, so why not complete the experience by offering their own pair of active shutter glasses? The PGD-150 glasses will come in a black frame with the IR sensor positioned right between the eyes. Basically, it looks like a much more modern version of the traditional, box-like paper red and blue glasses from the days of yore. You will be pleased to know that ViewSonic won’t charge an arm and a leg for the PGD-150 glasses unlike its competitors, as it will retail for less than $100.
