long-sightedness

World Encyclopedia | 2005 | Copyright

long-sightedness (hyperopia) Defect of vision that causes distant objects to be seen more clearly than nearby ones. In a long-sighted person, the focusing distance of the eyeball is too short and, as a result, light rays entering the eye strike the retina before they can be properly focused. Long-sightedness is corrected by convex lenses. See also myopia
