Question

Quizplus · Accepted Answer

The ciliary muscle is responsible for accommodation, which is the process of changing the shape of the lens in the eye to adjust focus on objects at different distances. Vergence eye movements involve the coordinated movement of both eyes to maintain binocular vision, but the ciliary muscle is not directly involved. Saccadic eye movements are rapid jerky movements used for visual scanning, and pursuit eye movements are used to track moving objects, but neither of these types of eye movements involve the ciliary muscle.
