"short-sightedness," 1727, medical Latin, from Late Greek myopia "near-sightedness," from myops "near-sighted," literally "closing the eyes," from myein "to shut" (see mute (adj.)) + ops (genitive opos) "eye" (see eye (n.)).
A defect of the eye that causes light to focus in front of the retina instead of directly on it, resulting in an inability to see distant objects clearly. Myopia is often caused by an elongated eyeball or a misshapen lens. Also called nearsightedness Compare hyperopia.
Nearsightedness. Myopia is a visual defect in which light that enters the eye is focused in front of the retina rather than directly on it, so that distant objects appear blurred. Myopia can be corrected with eyeglasses, contact lenses, or LASIK.
The term is often used to indicate an inability to see into the future: “The new policy is incredibly myopic, and puts future generations at a great disadvantage for the sake of a few short-term gains.”
