Also called: Farsightedness, Hyperopia, Myopia, Nearsightedness

Your cornea is the clear front part of your eye. It is like a window that controls and focuses the light coming into the eye. If your cornea has an irregular shape, the light does not focus properly. Everything looks blurry. This is a refractive error. Four common refractive errors are Myopia, or nearsightedness - clear vision close up but blurry in the distance Hyperopia, or farsightedness - clear vision in the distance but blurry close up Presbyopia - inability to focus close up as a result of aging Astigmatism - focus problems caused by the cornea Glasses or contact lenses can usually correct refractive errors. Laser eye surgery may also be a possibility.
