A student sitting on the last bench can read the letters written on the blackboard but is not able to read the letters written in his text book. Which of the following statements is correct ?

Options

A. The near point of his eyes has receded away
B. The near point of his eyes has come closer to him
C. The far point of his eyes has come closer to him
D. The far point of his eyes has receded away.

Explanation

To solve the question, we need to analyze the situation described: a student sitting on the last bench can read the blackboard but cannot read the letters in his textbook. This indicates a specific condition related to vision.

### Step-by-Step Solution:

1. **Understanding the Situation**: The student can read the blackboard (which is at a distance) but struggles to read the textbook (which is closer). This suggests that the student has no problem seeing distant objects but has difficulty with nearby objects.

2. **Identifying Vision Problems**: In normal vision, a person can see objects clearly at a distance (far point) and also at a close range (near point). The normal near point is about 25 cm from the eye.

3. **Analyzing the Symptoms**: Since the student can see the blackboard clearly but not the textbook, it implies that his near point is farther than 25 cm. This condition is known as hypermetropia (or farsightedness), where distant objects are seen clearly, but nearby objects appear blurry.

4. **Conclusion**: The correct statement regarding the student's vision is that he has a problem with his near point. Specifically, the near point has receded beyond the normal distance of 25 cm. Therefore, the correct answer is that the near point of his eye has receded away.

### Final Answer:
The correct statement is: The near point of the student's eye has receded away (indicating hypermetropia).
