Answer: (A)

Verified step by step guidance

1. Understand the context: The problem is related to changes in vision due to aging, specifically involving the lens of the eye.
2. Identify the key concept: As people age, the lens of the eye can become less flexible, a condition known as presbyopia.
3. Relate the concept to the problem: Presbyopia affects the ability to focus on near objects because the lens cannot change shape as easily to accommodate close vision.
4. Consider other options: Color blindness, focusing on distant objects, and blind spots are not typically related to the hardening of the lens due to aging.
5. Conclude with the most relevant effect: The hardening of the lens primarily affects near vision, making it difficult to focus on nearby objects.
