Question

The least distance of distinct vision for a normal person is about :

• A. 1 m
  1m1m
• B. $0.5m$
• C. $0.25m$
• D. $25m$

Answer 1

Answer: (C)

$0.25m$

The minimum distance, at which objects can be seen most distinctly without strain, is called the least distance of distinct vision. It is also called the near point of the eye. For a young adult with normal vision, the near point is about 25 cm which is equivalent to 0.25 m, thus option $C$ is correct.
