How do polarized 3D glasses work?

Polarized 3D glasses are the wave of the future, and have been used at theme parks for many years before being put into widespread use in current and recent features. Polarization occurs when a lens is oriented or created in a way that will only let certain types of light through, via microscopic slits in the lens. This form of 3D uses two different projectors to transmit the film onto a screen - both of those projectors possess a different polarization. You are then given a pair of polarized 3D glasses that are meant to interpret the images the projector provides you. When these two are played at the same time, your polarized 3D glasses only let in the particular image with the polarization that matches the lens. Thanks to this innovative technology, you can have a more vivid color image, dramatically improving the picture quality of most motion pictures.

Like with anaglyph images, special glasses are required to see these new 3D movies. Only vertically polarized light is allowed to pass through one lens and only horizontally polarized light is allowed to pass through the other lens. Two slightly different images are showed by two projectors using light polarized in one or the other direction. With this, a different image is viewed by each eye: just like what you can see in real life. Much more lifelike images is produced by using the polarization.

For 3d displays, the light from the image that it to be displayed to the left eye is polarized at a 135 degree angle. The light for the right eye is polarized at a 45 degree angle. The lenses are configured to allow light in from the correct angle and completely block light coming in at a 90 degree angle. Using this method the 3d monitor could display an image that looks grey to the naked eye, but when viewed through polarized lenses would be completely black to the left eye, and completely white to the right.
