Quizplus · Accepted Answer

The lens thickens or thins to focus incoming light, which is called accommodation. The iris controls the size of the pupil, but it is not directly involved in focusing light. Sensory adaptation refers to the process by which sensory receptors adjust to constant or repetitive stimuli, but it is not related to the functioning of the eye.
