Answer:
Hypermetropia is also referred to as hyperopia or long-sightedness or far-sightedness. Hypermetropia is the condition of the eyes where the image of a nearby object is formed behind the retina. Here, the light is focused behind the retina instead of focusing on the retina.
Hypermetropia is mainly caused due to certain structural defects in the retina. Structural defects include:
Small-sized eye-ball
Non-circular lenses
The cornea is flatter than usual
Defective blood vessels in the retina
Weakness in ciliary muscle
Changes in the refractive index of the lens
Alterations in the position of the lens or absence of lens
Low converging power of eye lens
