Why do I see in 3-d?

Like all human beings, you have ‘’binocular vision’’, meaning both your eyes face toward the front and provide your brain with two slightly offset images. Your brain processes the differences in these two images to create a perception of depth, or a three – dimensional view.

In order to see 3D and with stereo depth perception your brain has to use the visual information from both eyes. If the two eye views are too different and cannot be matched up, the brain will be forced to make a choice. It will reject all or part of the information from one eye. The brain can ignore, suppress or turn off visual information it cannot use.
