Hyperopia, also known as hypermetropia, or called far or long sightedness, is a defect of the eye in which an image is focused behind the retina. This causes an inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. With hyperopia the eyeball is too short, or the cornea is too flat, so images are focused behind the eye rather than on the retina at the back of the eye. Hyperopia can be corrected through the use of positive or convex lenses, such as glasses or contact lenses. It may also be corrected by laser refractive surgery. Hyperopia is often confused with presbyopia another eye condition causing blurred near vision.
