Binocular disparity

Binocular disparity refers to the slight difference in the images seen by each eye due to their horizontal separation. Each eye views an object from a slightly different angle, which results in two distinct images. The brain processes these differences to create depth perception, helping us judge how far away objects are. This phenomenon is essential for 3D vision and is why our perception of depth improves when using both eyes together, enhancing our ability to navigate and interact with the world around us.
