Pupils changes with age: which statement is correct?

Pupils changes with age: which statement is correct?

• A. Pupils decrease in size and become more reactive to light
• B. Pupils increase in size and become less responsive to light
• C. Pupils remain unchanged
• D. Pupils become more reactive to dark

Answer: (B)

As people age, the pupil tends to become smaller and its response to light slows down. This is called senile miosis. The iris muscles don’t dilate and constrict as quickly, so less light reaches the retina and adaptation to changing lighting is slower. So the correct understanding is a smaller pupil that is less reactive to light. The idea that the pupil increases in size with age isn’t typical, and statements claiming unchanged pupil size or increased reactivity to dark don’t fit how aging eyes usually change.
