The medical term for farsightedness is hyperopia. For optimum visual performance, our eyes must focus on faraway objects without exerting “extra” focusing effort. Far-sightedness is present when the eyes must focus to clear the distance vision. This results in a greater than normal focusing effort to maintain clear and comfortable close-range vision.
Most far-sighted children see clearly at distance. However, they achieve clarity by exerting a constant focusing effort at distance and close-range. Far-sighted adults, however, gradually see less clearly at distance because all adults naturally decrease focusing ability due to a secondary visual condition called presbyopia. Far-sighted eyes require eyeglasses and/or contact lenses to maintain clear and comfortable vision at all ranges. LASIK may also be considered for appropriate candidates.
