Overview
Myopia is a refractive
defect of the eye in which images focus in front of the retina. This
may be caused by a defect of the lens/cornea or when the shape of the eye is longer
then usual. Those with myopia are often described as nearsighted or short-sighted
in that they typically can see nearby objects clearly but distant objects appear
blurred because the lens cannot flatten enough. The
opposite of myopia is hyperopia or "farsightedness". Myopia
is the most common eyesight problem in the world. About one quarter of the adult
population in the United States has myopia. In places like Japan, Singapore and
Taiwan, as many as 44% of the adult population is myopic. <<backS |
