How do polarized 3d glasses work?

To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through circular polarizing filters of opposite handedness. The viewer wears 3D glasses which contain a pair of analyzing filters (circular polarizers mounted in reverse) of opposite handedness. read more

The glasses allow only one of the images into each eye because they contain lenses with different polarization. The polarized glasses allow only one of the images into each eye because each lens has a different polarization. read more

A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. read more

The viewer wears 3D glasses which also contain a pair of orthogonal polarizing filters. As each filter only passes light which is similarly polarized and blocks the orthogonally polarized light, each eye only sees one of the images, and the effect is achieved. read more
