Question

The farpoint of a myopic person is 100 cm in front of the eye. What is the nature and
power of the lens required to correct the problem?
​

Answer 1

Explanation:

The person is suffering from myopia and hence need a concave lens to correct the defect. The lens should be such that an object at infinity must form its image at the far point.  

Hence, f = - 100cm = - 1m

The power of the lens can be obtained as :

P = 1/f

P = 1/(- 1)

  = - 1D

Hope this helps.
