I am very interested 3D glasses lenses, they can bring much amazing impression when watching 3D ****es, What's the material of 3D glasses lenses? polarized lenses? if so, how do they work?

Polarized lenses, when watching 3-D ****e in a theater, the two lenses of Polarized glasses on your face are in a different angle, which lets polarized light goes in to your two eyes, thus the truth of 3-D glasses.
