Emmetropia is when light is focused exactly on the retina and vision is perfect. Farsightedness is called hyperopia. This condition occurs when the eyeball is smaller than normal and light rays from near objects do not focus properly on the retina at the back of the eye. A person with hyperopia can see distant objects more clearly than closer objects.
