B) retinal disparity
C) texture gradient
D) motion parallax

Question

Quizplus · Accepted Answer

Convergence, which refers to the degree to which our eyes turn inward to focus on a nearby object, is a distance cue that becomes less useful at longer distances. At 60 or 70 feet away, convergence no longer provides a significant cue to judge distance. Retinal disparity, texture gradient, and motion parallax are distance cues that remain effective at greater distances.
