Question

For a normal eye, the cornea of eye provides a converging power of 40 D and the least converging power of the eye lens behind the cornea is 20 D. Using this information, the distance between the retina and the cornea - eye lens can be estimated to be :

Accepted Answer

Correct answer: B. (b)Given P1 = 40 D P2 = 20 D P = P1 + P2 = 60 D Θ P = 1 0 0f(i n c m) So, f = 1 0 06 0 f = 53 = 1.67 cm.
