Three-Dimensional Image, or 3-D image, flat image enhanced to impart the illusion of depth. Humans perceive the world and the objects in it in three dimensions-breadth, width, and depth. This seemingly simple phenomenon is the product of a complicated set of interactions between our eyes and our brains that is still not entirely understood. Our eyes are spaced about 6 cm apart, which causes each eye to receive a slightly different image. The brain fuses these two images into a single 3-D image, enabling us to perceive depth.
Some of the Things 3-D Vision Helps You With: Throw,
catch or hit a ball Why some people have trouble seeing 3D In
order to view 3D stereo images you must have two eyes that work together
as a coordinated team. Two working eyes are definitely required.
If you are having trouble seeing 3D, the first thing you need to do is find out whether you have binocular vision and stereo vision. You've got to have stereo vision to experience depth perception and 3D illusions. Less than 5% of the population have severe visual disabilities that make stereo vision extremely difficult or impossible. This group includes those who have lost an eye or those with severe amblyopia (lazy eye) or strabismus (eye turns -- "crossed eyes" or "wall eyes"). Consider testing your own binocular vision with The Framing Game.
