Which statement describes changes in the eyes associated with aging?

• A. Increased flexibility of the eyes.
• B. Improved color discrimination.
• C. Loss of flexibility in the eyes.
• D. Lung changes with age.

Answer: (C)

Aging reduces the eye’s ability to change focus, known as accommodation. The lens becomes stiffer and the supporting muscles lose some effectiveness, so the eye can’t bend as easily to bring near objects into sharp focus. This loss of flexibility in the eyes is a common age-related change and is the reason many people need reading glasses as they get older. The other statements don’t fit because flexibility doesn’t increase with age, color discrimination doesn’t improve (it may decline somewhat due to lens changes), and lung changes have nothing to do with how the eye functions.
