Special Glasses

If you've ever been to a classic 3-D movie, then you remember the cardboard glasses with one blue and one red lens.

To create the 3-D illusion on a two-dimensional surface can be achieved by providing each eye with different optical information. If you've ever been to a classic 3-D movie, then you remember the cardboard glasses with one blue and one red lens. Another form of 3-D glasses utilizes polarized filters to create the illusion. Electronic 3-D spectacles use electronic shutters to create the image.

If you've ever played a Virtual reality game, you had to either put on goggles or a helmet. The virtual reality goggles or helmet had separate video screens so that each eye saw a different image. When this information is relayed to the brain, an illusion is created so that we see the flat image as three-dimensional. Sensors are also located in the helmet or goggles so that the image changes as we turn our heads. Some individuals have experienced motion sickness when wearing these items.
