Which of the following statements is NOT true of typical age-related changes in the human eye?

• A. The risk of developing cataracts increases as people age.
• B. The lens of the eye becomes less flexible, making it harder to focus on close objects.
• C. Color vision typically improves with age due to increased sensitivity of cone cells.
• D. Older adults often experience a decrease in pupil size, which can reduce the amount of light entering the eye.

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the typical age-related changes in the human eye by reviewing common physiological changes such as cataract development, lens flexibility, pupil size, and color vision.
2. Step 2: Recognize that cataracts, which are clouding of the lens, become more common with age, increasing the risk of vision impairment.
3. Step 3: Know that the lens of the eye loses flexibility over time, a condition called presbyopia, which makes focusing on close objects more difficult.
4. Step 4: Identify that pupil size generally decreases with age (a process called senile miosis), reducing the amount of light entering the eye and potentially affecting vision in low-light conditions.
5. Step 5: Evaluate the statement about color vision improving with age; understand that typically, color vision declines due to changes in the cone cells and other ocular structures, so the claim that it improves is NOT true.
