Question

an eye has a far point of to infinity? calculate the power of lens and determine the nature of the vision​

Answer 1

Answer:

For a normal eye, the far point is at infinity and the near point of distinct vision is about 25 cm in front of the eye. The cornea of the eye provides a converging power of about 40 dioptres, and the least converging power of the eye - lens behind the cornea is about 20 dioptres
