The ability of the eyes to make jump movements.

Explanation:
Jump movements are rapid, ballistic shifts of the eyes that quickly relocate the gaze to a new target. These quick, high-velocity movements are called saccades and are used when scanning a scene or moving from one object to another, such as reading or looking around a room. In contrast, pursuits are smooth, continuous tracking of a moving object and don’t involve sudden jumps. Vergence adjusts the eyes inward or outward to fuse image focus at different depths, not to shift gaze abruptly. Accommodation is the lens’ focus adjustment, not an eye movement. So the ability to make jump movements is best described by saccades.
