Suspensory ligaments are tiny fibres in the eye that connect the ciliary muscle to the lens. They help change the shape of the lens during a process called accommodation, which allows the eye to focus on objects at different distances. When the ciliary muscle contracts or relaxes, it changes the tension on the suspensory ligaments, causing the lens to become thinner or thicker. This adjustment is essential for clear vision when looking at near or distant objects.
