Stereopsis is a binocular cue that enables us to perceive depth and form by comparing the slightly different images received from each eye. The brain combines these images to create a single, three-dimensional perception.

Convergence is a binocular cue where the brain uses the inward movement of the eyes to determine the depth and nearness of an object. When an object moves closer, the eyes turn inward (converge) to maintain a single image.

Binocular disparity refers to the difference in the retinal images of the same object between the two eyes. This cue allows the brain to perceive depth by calculating the horizontal displacement of objects based on the differences in where they fall on the retina.

Relative size is a binocular cue that helps us perceive depth by comparing the size of objects in the visual field. When two objects of similar size are placed at different distances, the one that appears smaller is perceived as being farther away.

Vertical position, also known as vertical disparity, is a binocular cue that relies on the fact that our eyes are horizontally displaced. By comparing the vertical position of objects in the visual field, our brain can determine their relative depth and distance.
