Question

a person with a myopic eye cannot see objects beyond 1.2 m distinctly what should be the type of the corrective lens used to restore proper vision​

Answer 1

A person with a myopic eye cannot see objects beyond 1.2 m distinctly because, In a myopic eye, the image of a distant object is formed in front of the retina. This defect can be corrected by using a concave lens

Answer 2

Answer:

Given that,

The person can't see objects beyond 1.2 m directly

So, in order to view the distances beyond 1.2 m, the focal length of the lens should be 1.2 m.

Now, the power

P= 1/f

P= 1/1.2

P=0.83D

So, the person suffers from Myopia, the corrective lens will be concave or diverging lens.

Hence, the power is 0.833 D
