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 :
Text Solution
Verified by ExpertsThe correct answer is:
B
Given P 1 = 40 D
P 2 = 20 D
P = P 1 + P 2 = 60 D
P = 
So, f = 
f = 
= 1.67 cm.
