Quizplus · Accepted Answer

As people age, the muscles controlling the pupil weaken, making it harder for the eyes to adjust to changes in light levels. The other statements are incorrect. The lens actually becomes less elastic and loses some of its ability to change shape, which can lead to a decrease in visual acuity. Color discrimination also tends to decline with age.
