Question

Angle of vision of a healthy adult human is

• A. 10°
• B. 60°
• C. 90°
• D. 40°

Answer 1

The Correct Option is B

To solve the problem, we need to determine the angle of vision of a healthy adult human.

1. Understanding the Angle of Vision:
The angle of vision is the maximum angle through which a healthy human can clearly see objects without difficulty. This is typically determined by the visual range of the eyes.

2. General Knowledge:
For a healthy adult human, the normal angle of vision is approximately $60^\circ$. This means a person can comfortably view an object within a $60^\circ$ angle from their central line of sight.

Final Answer:
The angle of vision of a healthy adult human is $ {60^\circ} $.
