Full Lens Description
[Continued from above] . . . keeps it under constant tension. As a result, the lens can assume a globular shape. However, the suspensory ligaments attached to the edges of the capsule are also under tension, and as they pull outward, the capsule and the lens inside are kept somewhat flattened. If the tension is relaxed, the elastic capsule rebounds, and the lens surface becomes more convex (rounded). Such changes occur in the lens when the eye is focused to view a close object. This adjustment is called accommodation, and is a function of the ciliary muscles.
