Highlighting the Benefits of 3D Viewing – January 2013
Binocular vision is the ability to align both eyes accurately on an object and combine the visual images from each eye into a single, in-depth perception. It is the reliance on binocular vision that makes us perceive 3D imagery on TVs and game consoles.
There are actually many technical variations on 3D imagery for TV. The display either shows two perspectives of an image to your eyes at different times (active glasses) or both perspectives are on the screen at the same time but each eye is only able to see one perspective because of eyewear or a special filter on the screen.
