Final answer:
The lens is attached to the ciliary body by transparent fibers called suspensory ligaments or zonule fibers, which are essential for the eye's focusing mechanism.
Step-by-step explanation:
The lens of the eye is attached to the ciliary body by transparent fibers known as suspensory ligaments or zonule fibers. These fibers play a crucial role in the eye's ability to focus light on the retina, which happens when the ciliary body adjusts the lens shape for focusing. The lens, working alongside the cornea, acts to form a real image on the retina, especially focusing images clearly on the fovea, which is the part of the retina best equipped for sharp central vision.
