When you look at a distant object, the lines of vision from your eyes are parallel. You are normally not aware of it, but the muscles attached to the eyeball feed information on eye position to the brain to help it judge distances under 50 feet. This describes the binocular depth cue known as
A) accommodation.
B) motion parallax.
C) convergence.
D) linear perspective.
