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

Question

Quizplus · Accepted Answer

The ciliary body is a ring of muscle tissue that surrounds the lens and is responsible for changing the shape of the lens to allow for focusing on objects at varying distances. When the ciliary body contracts, it pulls on the lens, causing it to become more rounded for close-up vision. When the ciliary body relaxes, the lens becomes flatter for distant vision.
