Question

What is the primary cause of presbyopia, as described in the text?
Options
A The cornea's surface is not spherical.
B The crystalline lens grows throughout a person's life, and ciliary muscles are less able to distort it.
Correct Answer
C Rays from an object at infinity focus in front of the retina.
D The image of an object at infinity is formed behind the retina.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text explains, "The range of accommodation gradually diminishes with age because the crystalline lens grows throughout a person's life and the ciliary muscles are less able to distort a larger lens. For this reason, the near point gradually recedes as one grows older. This recession of the near point is called presbyopia."

Hint

Presbyopia is specifically linked to age and the eye's internal structures responsible for accommodation.
