What is hypermetropia or farsightedness? What is the near point of a normal eye and a hypermetropic eye ?

Explanation

The defect of vision due to which a person can see distant-objects clearly but cannot see nearby objects distinctly is called hypermetropia or far-sightedness.
In a normal eye, the near point is about 25 cm. Rays coming from an object at 25 cm from the eye lens, are focussed on the ratina.
In turn, the retina conveys a message to the brain via optic nerve.

A hypermetropic eye has near point farther away from normal near point (25 cm).
A person with hypermetropia has to keep reading material much beyond 25 cm from the eye for comfortable reading.
This is because light rays from the closed object are focussed at a point behind the retina.
