What is binocular vision?
Q: What is binocular vision?
A: Binocular vision is when both eyes are used together to create a visual field which is put together by the brain with input from both eyes.
Q: How much of the horizontal field of view can humans see with two eyes?
A: Humans have a maximum horizontal field of view of about 200 degrees with two eyes.
Q: What does parallax provide in terms of depth information?
A: Parallax provides precise depth information, called stereopsis.
Q: What is binocular fusion?
A: Binocular fusion is when a single image is seen even though each eye has its own image of an object.
Q: What is stereopsis?
A: Stereopsis is the impression of depth we get when we look at a scene with both eyes. It uses differences in the images seen by each eye to calculate depth in the visual scene.
Q: How does motion parallax work?
A: Motion parallax works by creating differences in the single retinal image over time similar to binocular disparity when an observer views a scene with only one eye while moving.
