What term describes the eyes' ability to track or follow an object smoothly?

• A. Pursuit
• B. Depth perception
• C. Visual concentration
• D. Visualization

Answer: (A)

The ability of the eyes to smoothly follow a moving object is pursuit, specifically smooth pursuit. When a target moves, the brain engages a controlled, continuous eye movement that keeps the target’s image aimed on the fovea, allowing a fluid, uninterrupted tracking. If the target is fast or changes direction abruptly, the eyes may insert small corrective saccades, but the goal remains to maintain smooth, steady tracking.

Depth perception is about judging distance and three-dimensional relationships, not tracking motion. Visual concentration and visualization are general terms not used to describe this specific eye-movement function.
