Lenses that correct farsightedness
Lenses that correct farsightedness are different from that correct nearsightedness,Eyeglass lenses that correct myopia (also called minus lenses) have the opposite shape: they are thinnest at the center and thickest at the edge. Though the slimming effect of aspheric lenses is less dramatic in minus lenses, it still provides a noticeable reduction in edge thickness compared with conventional lenses for myopia correction.Lenses that correct nearsightedness are on the contrast.
