The zonular fibers, also known as zonules or zonular ligaments, play a crucial role in supporting the lens of the eye and are indeed attached to the ciliary processes. The ciliary body, which produces aqueous humor and holds the lens in place, contains these processes that project inward and are responsible for anchoring the zonular fibers.

When the ciliary muscle contracts, it adjusts the tension on the zonular fibers, allowing for changes in the shape of the lens, which is essential for focusing on objects at various distances—this process is called accommodation.

The attachment of the zonular fibers to the ciliary processes ensures that the lens is properly positioned within the eye and that its curvature can be altered effectively for clear vision. Understanding this relationship is fundamental to grasping how the eye adjusts focus, which is a critical aspect of visual function.
