Quizplus · Accepted Answer

The lens is responsible for changing its shape in order to focus incoming light onto the retina, allowing for clear vision. The cornea also plays a role in focusing incoming light, but it does so by refracting the light rather than changing shape. The fovea and retina are both involved in processing the incoming light once it has been focused by the lens and cornea.
