8th Grade Cow Eye Dissection |

The suspensory ligaments are connecting tissues composed of thin fibers. They connect the ciliary body to the eye's lens. When the ciliary muscle contracts, the tension in the suspensory ligaments is changed and they pull or push the lens to change its shape. As the lens changes its shape, we are able to adjust our focus to clearly see objects at different distances from our eyes.
When focusing the eye, the lens is pulled into different shapes by the suspensory ligaments as the ciliary body flexes and relaxes. The ciliary body contains the ciliary muscle, otherwise known as the muscle of accommodation. The eye views distant objects with the lens stretched and flattened and less convex because the lens does not need to bend the light as much if it comes from a far away distance. For viewing near objects the lens in more relaxed and more convex to bend the light from the object more sharply.
