Binocular Cues

Visual information taken in by both eyes that aids in depth perception, including stereopsis, convergence, and the vergence movement.

Monocular Cues

Visual information that allows for perception of depth and distance using one eye.

Depth Perception

The visual ability to perceive the world in three dimensions and judge the distance of an object.

Binocular Depth Cue

Visual information taken in by two eyes that enable us to perceive depth and distance.
