Myopia, sometimes called near-sightedness or short-sightednessTerm "short-sightedness" is more frequently used as "lack of foresight", is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed. This may be caused by a defect of the cornea (generally where the cornea protrudes too far outward from the eye) or from elongation of the eye structure itself (generally the eye is too long). Those with myopia typically can see nearby objects clearly but distant objects appear blurred. The opposite defect of myopia is hyperopia or "far-sightedness" or "long-sightedness" — this is where the cornea is too flat or the eye is too short.
Worldwide, myopia is the most common eyesight problem. About one quarter of the adult population in the United States is myopic. In some countries, such as Japan, Singapore and Taiwan, up to 44% of the adult population is myopic.
Mainstream ophthalmologists and optometrists most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, such as LASIK. The corrective lenses have a negative dioptric value (i.e. are concave) which compensates for the excessive positive diopters of the myopic eye.
