An old person requires spectacles for

Options

A. Reading
B. Distant vision
C. Both A and B
D. Astigmatism.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks why an old person requires spectacles. This typically relates to common vision problems associated with aging.

2. **Identifying Common Vision Problems**: As people age, they often experience two primary vision issues:
- **Nearsightedness (Myopia)**: Difficulty seeing distant objects clearly.
- **Farsightedness (Hyperopia)**: Difficulty seeing nearby objects clearly.

3. **Recognizing Presbyopia**: In older adults, a common condition known as **presbyopia** occurs, which is the loss of the eye's ability to focus on nearby objects. This condition often leads to the need for reading glasses or bifocal lenses.

4. **Analyzing the Options**:
- **Option A (Reading)**: This is correct because older individuals often struggle with reading due to presbyopia.
- **Option B (Distant Vision)**: This is also correct as some older individuals may have difficulty seeing distant objects.
- **Option C (Both A and B)**: Since both reading and distant vision issues are common in older adults, this option is correct.
- **Option D (Astigmatism)**: While astigmatism is a vision issue, it is not specifically related to aging and is not the primary reason older individuals require spectacles.

5. **Conclusion**: The correct answer is **Option C (Both A and B)**, as older individuals may require spectacles for both reading and distant vision due to conditions like presbyopia.
