retinal disparity

Retinal disparity refers to the slight difference in the images experienced by our left and right eyes, due to their horizontal separation. Because each eye views a scene from a slightly different angle, the brain compares these two images to determine how close or far away objects are. This process helps us perceive depth and judge distances accurately, enabling us to navigate our environment effectively. Retinal disparity is a key component of binocular vision and plays a vital role in stereoscopic depth perception.
