Binocular Cues: Convergence

Binocular cues are involved in depth perception, and involve the use of both of our eyes.  One binocular cue is convergence, which is how much the eyes converge inwards when looking at an object.  The more inwardly the eyes are focused, the closer the object.  For example, when looking at a globe from a closer distance the eyes are more inwardly angled.  When looking at a globe from a farther distance, the eyes are not as sharply angled.
