The statement that is true about changes in vision in adulthood is: "The muscles controlling the pupil weaken."

Here's why:

1. The lens does not narrow and become more elastic. In fact, the opposite is true. As we age, the lens of the eye thickens and loses its elasticity, leading to a common condition in adults over 40 known as presbyopia, which results in difficulty focusing on close objects.

2. Visual acuity does not increase. It generally decreases with age. Many adults over the age of 40 begin to experience presbyopia, and by the age of 60, most have a mild to moderate decrease in visual acuity.

3. Color discrimination does not improve. It generally decreases with age. This is due to changes in the lens and the cells of the retina. The lens yellows with age, and this can make it more difficult to distinguish between shades of color.

4. The muscles controlling the pupil do weaken. This can result in the pupil reacting more slowly in response to changes in light. As a result, older adults may find it more difficult to adapt to different levels of light and may be more sensitive to glare.
