Hyperopia, also known as farsightedness, is a condition in which a person can see distant objects more clearly than near objects. Hyperopia usually occurs when an eyeball is smaller than normal. Due to the smaller eyeball, light rays from near objects focus at the back of the retina. The result is blurred vision. Mainly hyperopia is inherited. As the young children tend to be slightly hyperopic. As the eye grows, eyeball becomes longer and hyperopic eventually lessens. Presbyopia, a condition with similar symptoms, has an entirely, has an entirely different cause and is related to ageing.
Light entering the eye is focused behind the Retina. It is caused by a flatter than normal Cornea, or an eye that is shorter than normal.
