| farsightedness |
Refractive error. Focusing defect in which an eye is underpowered; light rays coming from a distant object strike the retina before coming to sharp focus, blurring vision. Farsighted people expend focusing effort to see clearly in the distance, and close-up vision is blurred because it takes even more focusing effort. Corrected with additional optical power, which may be supplied by a plus lens (spectacle or contact) or by excessive use of the eye's own focusing ability (accommodation).
