Helps keep the eye in place so it doesn't pop out of its socket.
The eye lens is kept in place by ciliary muscles. These muscles can contract or relax.If the ciliary muscles contract or relax the focal length of the eye lens becomes large or small.Or in other words the function of the eye lens is to increase or decrease the focal length of the eye lens.
The process by which the lens of the eye changes its curvature is called accommodation. This involves the ciliary muscles surrounding the lens contracting or relaxing to change the shape of the lens, allowing the eye to focus on objects at different distances.
Muscles in the eye surrounding the lens contract stretching it out, flattening it; or relax, letting it thicken. These changes in shape refocus the lens.
The object pulled on by ciliary muscles to bend light is the lens of the eye. The ciliary muscles change the shape of the lens, which allows the eye to focus on objects at different distances.

For the eye, the lens becomes thinner?
The ciliary muscles are responsible for changing the shape of the lens in the eye so that you can focus on near or distant objects. When these muscles contract, they thicken the lens for near vision, and when they relax, the lens becomes thinner for distant vision.
The lens of the eye also called the crystalline lens.
The ciliary muscles which relax to help the eye see far away by expanding and pulling the lens and stretching it and contract to scrunch the lens up and see close up. By shrinking the lens, they allow it to bend light at a more drastic angle to focus on close up images.
The muscles in your eye are contracting and relaxing, instinctively attempting to refocus the lens.
Ciliary Muscle
No, to focus ligh, muscles in the eye change the length and thickness of the lens.
