is it ciliary muscles

Expert Answer:

To focus on distant objects, the ciliary muscles are relaxed causing the eye lens to become thin and thus increasing the focal length of the eye lens. To focus on nearby objects, the ciliary muscles contract causing the eye-lens to become thick and thus decreasing the focal length of the eye-lens. In this manner, by changing the focal length of eye-lens, the images of objects at different distances are brought to focus on the retina.
