Binocular Cues

Definition

Binocular cues refer to the depth cues that depend on the use of both eyes. One key binocular cue is retinal disparity.

Analogy

Imagine you're trying to catch a ball thrown towards you; your brain uses input from both eyes - slightly different images due each eye's position - then combines these images into one 3D image allowing you accurately judge where the ball will land. That's how binocular cues work!

Related terms

Retinal Disparity: This refers to the slight difference in two retinal images due to angle from which each eye views an object.

Convergence: This is another binocular cue where your brain calculates how much your eyes must turn inward in order for you see an object clearly.

Stereopsis: It's a term used for describing perception of depth and 3-dimensional structure obtained on basis of visual information deriving from two eyes by individuals with normally developed binocular vision.
