Hyperopia

n. far-sightedness, ability to see distant objects more clearly than near ones

Hyperopia, also known as hypermetropia or colloquially as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.

Hyperopia is the condition of the eye where incoming rays of light reach the retina before they converge into a focused image. [more]Hyperopia - Community and Resources
