Description : Myopia, or nearsightedness, is a refractive error of the eye. Light rays from a distant
object are focused in front of the retina and those from a near object are focused
in the retina; therefore distant objects are blurry and near objects are clear (summary
by Kaiser et al., 2004). For a discussion of genetic heterogeneity of myopia, see
