Ramesh cannot see distinctly objects kept beyond 2 m. This defect can be corrected by using a lens of power

Options

  1. A+ 0.5 D
  2. B– 0.5 D
  3. C+ 0.2 D
  4. D– 0.2 D

Correct answer

B. – 0.5 D

Step-by-step solution

This condition is know as near sightedness. This defect can be corrected by using the concave laws of power –0.5 D.
