NVIDIA's 3D Vision
Unlike many of the other 3D stereoscopic solutions out there, NVIDIA uses active shutter glasses for 3D Vision. Unlike passive solutions, which are considerably less expensive as they rely on simple polarized filters, these active shutter glasses essentially act as two displays – one for each eye – with each lens shutting off every other frame. The lenses constantly alternate between on/off back and forth for each eye, with one lens allowing light to pass through so you can see, while the other is blacked out. As a result, each eye sees alternating frames, with each frame slightly offset from the previous frame. This creates the illusion of 3D to our eyes, even though you’re actually looking at a 2D image.
