Answer 2

If Ciliary muscles do not perform contraction and expansion, more light enters our eyes, potentially damaging them.

• The ciliary muscle is an intrinsic muscle of the eye that is formed as a ring of smooth muscle in the middle layer of the eye, known as the uvea (vascular layer). It regulates the flow of aqueous humour into Schlemm's canal and controls accommodation for viewing objects at different distances.
• If the ciliary muscles of the eye are damaged, the person will have blurred vision and will be unable to focus properly.
• It contracts and relaxes to "change the focal length" of the lens, allowing for both short and long-distance vision. If the damage is not repaired, the person may lose their entire vision.
