Common vision problems
Hyperopia/Farsightedness
Also called farsightedness, or hypermetropia, Hyperopia 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 toward the eye, the eye must increase its power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred. It results from the eyeball being too short from front to back, causing images to be focused behind the retina.
It is also sometimes referred to as farsightedness, since in otherwise normally-sighted persons it makes it more difficult to focus on near objects than on far objects and is the opposite of myopia.
