How do 3D glasses work? (Polarization, Part 2)

Modern 3D glasses make use of a piece of technology called polarizers. They use a quarter-wave plate on the front of their lens and a linear polarizer on the back of the lens. 3D movies rapidly switch between a left-eye view and a right-eye view to trick your brain into using depth perception, with each view having a different orientation of circularly polarized light. The quarter-wave plates on each lens only let in a certain orientation of polarized light so each eye will only receive their intended view. The linear polarizers on the back ensure that the light reaches your eyes in phase with each other. This is the follow-up video on polarization.
