3D glasses work by filtering separate images to each eye that are combined by the brain into a 3D image. There are different types of 3D glasses like anaglyph, polarized, and LCD shutter glasses. Anaglyph glasses filter red and blue images to each eye. Polarized glasses use lenses with different polarizations to filter images. LCD shutter glasses rapidly block each lens to match images on the screen. Together, the brain perceives 3D depth from binocular vision.
