Which visual structure demonstrates decreased pupil size; slower dilation after exposure to light, and decreased near vision and accommodation as the patient ages?

Question

Quizplus · Accepted Answer

The iris controls the size of the pupil, which decreases in size after exposure to light. As an individual ages, the iris becomes less responsive, resulting in slower changes in pupil size and decreased near vision and accommodation. The lens and cornea do not directly control pupil size or accommodation, and the retina is responsible for sensory processing of light rather than controlling visual functions.
