Zonules of Zinn

The Zonules of Zinn, also known as ciliary fibers, are tiny, transparent strands of tissue that connect the eye's lens to the ciliary body. They act like a suspension system, holding the lens in place and allowing it to change shape for focusing on objects at different distances. When the ciliary muscles contract or relax, these fibers help the lens adjust its thickness, enabling clear vision. Their proper function is essential for sharp eyesight, especially during activities like reading or focusing on distant objects.
