The far point of a myopic person is 150 cm in front of the eye. Calculate the focal length and the power of lens required to enable him to see the distant objects clearly.

Far point of the myopic person = 150 cm. For him to be able to clearly see very distant objects, the image should be made at 150 cm in front of the eye.
Using lens formula,
Therefore, a concave lens of power -0.66 D has to be used.
