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?
In a normal eye, the far point is infinity. The lens used should be such that an object at infinity, forms a virtual image at 1.2 m.
A concave (or divergent) lens of focal length 1.2 m and power- 0.83 D should be used to restore proper vision.
