Hyperopia (Farsightedness)

farsightedness-hyperopiaHyperopia, also known as farsightedness, longsightedness or hypermetropia, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or the lens cannot become round enough), causing difficulty focusing 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 optical 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.

Known as plus or convex, these contact lenses are thicker at the center and thinner at the edges. They bend the light toward the center and move the focal point forward so that light is focused on, rather than behind, the retina.
