Question

What is the power of normal eye lens?

Answer 1

n humans, the total optical power of the relaxed eye is approximately 60 dioptres. The cornea accounts for approximately two-thirds of this refractive power (about 40 dioptres) and the crystalline lens contributes the remaining one-third (about 20 dioptres).)

Answer 2

Answer:;In my opinion ,the correct answer is+4 D.

Explanation: The focal length of normal eye is 25 cm.

Since we know that P = 1/f in m and 100/f in cm.

Therefore P= 100/25 = +4D
