Questions: Question 9 (1 point) 9 At what age does difficulty in focusing close up typically begin? 30 s 40 s 50s 60 s

The answer is the second one (40s): difficulty in focusing close up typically begins in the 40s.

Explanation for each option:

• 30s: It is less common for people in their 30s to experience significant difficulty in focusing close up. This condition, known as presbyopia, usually starts later.
• 40s: This is the most common age range when presbyopia begins. The lens of the eye becomes less flexible, making it harder to focus on close objects.
• 50s: While presbyopia continues to progress in the 50s, it typically begins earlier, in the 40s.
• 60s: By the 60s, most people will have already experienced presbyopia for some time. It is not the typical age when it begins.

Summary: Difficulty in focusing close up, known as presbyopia, typically begins in the 40s.
