In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings.
The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a single image.
Stereopsis is the component of depth perception retrieved by means of binocular disparity through binocular vision. [1] It is not the only contributor to depth perception, but it is a major one. Binocular vision occurs because each eye (left and right) receives a different image due to their slightly different positions in one's head.
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes ( binocular vision) when viewing distant objects.
Birds with eyes on the sides of their heads have a wide field of view, useful for detecting predators, while those with eyes on the front of their heads, such as owls, have binocular vision and can estimate distances when hunting.
For example, binocular vision, which is the basis for stereopsis and is important for depth perception, covers 114 degrees (horizontally) of the visual field in humans; [8] the remaining peripheral ~50 degrees on each side [7] have no binocular vision (because only one eye can see those parts of the visual field).
