Convergence refers to a binocular cue used in depth perception that occurs when the eyes turn inward to focus on a nearby object. The closer the object, the more the eyes converge, allowing the brain to interpret the degree of convergence as a cue for how far away the object is. This process helps us perceive depth and distance accurately, making option C the correct choice.

Other options do not accurately describe convergence. Enhancing contrast, detecting speed, and improving peripheral vision involve different visual processes that do not relate to the way our eyes work together to perceive depth.
