Binocular and monocular cues

Binocular and monocular cues are how we convert the two different retinal images received by our eyes into a single, three dimensional image. Binocular cues are those that are depth related and dependent on two eyes. It consists of disparity, the difference between two objects, and convergence, how far the eyes look inward when observing an object. The more the observer looks inward, the closer an object is. Monocular cues are those that focus on distance and are present in the view of either eye alone. Monocular cues consist of size, interposition (the partially blocked view of one object by another), how clearly something is seen, the gradient of an object’s texture, its height, motion present, lighting, and linear perspective.
