Detailed Solution

If a person can not see the object kept beyond

2 m

clearly, then this defect can be corrected by using a lens of

- 0.5 D

.
Myopia is an eye defect in which the person can see nearby objects clearly, but cannot see far objects clearly. If a person cannot see objects distinctly kept beyond

2 m

, then the person is suffering from Myopia.
The far point is equal to

2 m

, and therefore, a concave lens should be used of focal length

- 2 m

. Then the power of the lens is equal to,

P = \frac{1}{f}

P = \frac{1}{- 2}

P = - 0.5 D

A concave lens of power
