Hypermetropia is an eye condition in which the eyeball is too short and does not allow proper focusing.
In the farsighted eye, light rays from a distance are focused beyond the retina, thus making vision blurry.
Anatomically, most children at birth have mild hypermetropia, which is to be considered physiological and is usually compensated by the accommodative process, an autonomous mechanism of the visual apparatus, which involves increasing the curvature of the anterior surface of the lens through the ciliary muscle.
When the defect is mild, the eye, up to about age 40, is able to naturally correct the defect by perpetually activating the accommodation mechanism; in this way vision is as clear and sharp as in a normal eye, although this continuous strain on vision often strains the eyes in distance vision.
