Depth perception is the  ability to perceive the world in three  () and the distance of an object. Depth sensation is the corresponding term for animals, since although it is known that animals can sense the distance of an object (because of their ability to move accurately, or to respond consistently, according to that distance), it is not known whether they “perceive” it in the same subjective way that humans do.

Depth perception arises from a variety of depth cues. These are typically classified into  cues that are based on the receipt of sensory information in three dimensions from both eyes and  cues that can be represented in just two dimensions and observed with just one eye. Binocular cues include , eye convergence, , and yielding depth from  through exploitation of . Monocular cues include size: distant objects subtend smaller  than near objects, grain, size, and motion
