Which muscle is responsible for changing the shape of the lens to focus on near objects?

  1. Ciliary muscle

  2. Iris muscle

  3. Rectus muscle

  4. Scleral muscle

The correct answer is: Ciliary muscle

The ciliary muscle is responsible for changing the shape of the lens to focus on near objects. When the ciliary muscle contracts, it causes the lens to become more rounded, which is necessary for focusing on close objects through a process called accommodation. The other muscles listed are not directly involved in the process of changing the shape of the lens for near vision.
