Quizplus · Accepted Answer

The lens is responsible for focusing light onto the retina by changing its shape to adjust for near or far objects. The cornea and pupil also play a role in focusing light, but the primary responsibility falls on the lens. The iris controls the size of the pupil, which affects the amount of light that enters the eye, but it does not directly focus light onto the retina.
