Ciliary body
From Biocrawler, the free encyclopedia.
There are two sets of ciliary muscles in the eye. They are near the front of the eye, above and below the lens. They are attached to the lens by connective tissue called zonular fibers, and are responsible for shaping the lens to focus light on the retina.
When the ciliary muscles flex, they flatten the lens, strengthening the focus for farther objects. When they extend, the lens becomes more convex, strengthening the focus for closer objects.
