Question

Quizplus · Accepted Answer

The lens is responsible for focusing incoming light rays onto the retina, specifically by changing shape to adjust for distance and creating a clear image on the retina. The iris controls the size of the pupil, which can affect the amount of light entering the eye, but does not directly focus light. The ciliary body is responsible for changing the shape of the lens, but again, not for directly focusing light.
