Question

Quizplus · Accepted Answer

When the lens accommodates for near vision, the ciliary muscles contract, which causes the suspensory ligaments to become loose. This releases the tension on the lens, allowing it to become more curved or convex. This shape change allows the eye to focus on nearby objects. Therefore, choice C is the best answer as it correctly describes the action of the ciliary muscles and suspensory ligaments during accommodation for near vision.
