Which of the following is listed as a functional change affecting the eyes?

• A. Irritation and infection of the eyes
• B. Improved tear production
• C. Increased accommodation
• D. Enhanced night vision

Answer: (A)

Aging commonly affects the eyes by reducing protective tear production, which leads to irritation and infections. When tear production declines, the eye surface becomes drier and more irritated, creating a environment where microbes can cause infections more easily. The other options describe changes that are not typical with aging: tear production does not improve, accommodation (the ability to focus on near objects) generally decreases with age, and night vision usually diminishes rather than improves.
