Question

what is the power of the eye lens of a normal eye when it is focused at its
a) near point
b) far point
take the distance between lens and retina to be approximately equal to diameter of the eye

Answer 1

Answer:

For a normal eye, near point of distinct vision = 25 cm. To see objects at infinity, the eye uses its least converging power = 40 + 20 = 60 dioptres. This gives the rough idea of the distance between the retina and cornea eye-lens. the power of the eye lens = 64 - 60 = 24 dioptre

Answer 2

Answer:

The human eye works on the refraction of light through a natural convex lens made of transparent living matter and enables us to see things around us. In this article, we will see how the eye works, how we see color, how the defects of the eye are removed, etc.
