Question

The far point for normal vision is:

• A. 25 mm
• B. 25 cm
• C. 25 m
• D. Infinity

Hint:

For a person with normal vision, the farthest point they can see clearly without accommodation is at infinity.

Answer 1

The Correct Option is D

Step 1: Understanding the far point of normal vision.
The far point of vision is the maximum distance at which an object can be seen clearly without accommodation.
For a person with normal vision, the farthest distance they can see clearly is infinity.
Step 2: Analyzing the options.
- 25 mm (Option A): This is extremely short and incorrect.
- 25 cm (Option B): This is incorrect; this is closer to the near point of vision.
- 25 m (Option C): This is incorrect, as normal vision extends far beyond this range.
- Infinity (Option D): This is correct because a normal human eye can focus on objects at an infinite distance.

Step 3: Conclusion.
- The far point for normal vision is at infinity.
- Hence, the correct answer is (D) infinity.
