What structure changes the shape of the lens for far and near vision?

Question

Quizplus · Accepted Answer

The ciliary body is responsible for changing the shape of the lens for far and near vision by controlling the tension on the suspensory ligaments that hold the lens in place. When the ciliary muscles contract, they relax the tension on the suspensory ligaments, allowing the lens to thicken and increase its refractive power for near vision. When the ciliary muscles are relaxed, the tension on the suspensory ligaments increases, flattening the lens and decreasing its refractive power for far vision.
