Stereoscopic vision

Definition

Stereoscopic vision is the ability to perceive depth and three-dimensional structure obtained on the basis of visual information deriving from two eyes. It allows for accurate judgment of distance and spatial relationships between objects.

5 Must Know Facts For Your Next Test

1. Stereoscopic vision relies on binocular disparity, where each eye views an object from a slightly different angle.
2. It is crucial for activities that require precise depth perception, such as hunting and navigating complex environments.
3. Many vertebrates, including humans, birds of prey, and some primates, possess stereoscopic vision.
4. The brain processes the images from both eyes to create a single three-dimensional perception.
5. In vertebrates with forward-facing eyes, stereoscopic vision enhances their ability to judge distances accurately.
