How Do 3-D Glasses Work?? A :  The reason why people war 3-D glasses is to feed a different images into your eyes. The screen that you looking at displays two images and the glasses cause one of the images to enter one eye and then the other image to enter the other eye. They have two different kinds of 3-D systems. These two different systems are called Polarization and Red/Green or Red/Blue. Polarization can’t work on regular TV so that’s why we use Red/Blue (or green).   * Red/Blue or Red/Green Glasses-On the TV screen the images are red and blue. The filters on the glasses allow only one image to enter each eye and you brain does the rest. You can’t be watching a colored movie while you’re using colored glasses so polarized glasses work better with that.
