Question

The shape of the lens is controlled by the
A) pupillary sphincter muscles.
B) pupillary radial muscles.
C) ciliary muscles.
D) iris.
E) cornea.

Accepted Answer

The shape of the lens is controlled by the ciliary muscles. These muscles connect to the lens via the suspensory ligaments and can alter the shape of the lens to allow for changes in focus. The pupillary sphincter and radial muscles control the size of the pupil, the iris controls the amount of light entering the eye, and the cornea primarily helps to refract light entering the eye.
