Progressive lenses as used in eyeglasses, or spectacles, a farsighted vision zone having an optical power corresponding to that required for viewing distant objects; a nearsighted vision zone having an optical power corresponding to that required for viewing near objects; and an intermediate vision zone between and progressively connecting the farsighted vision zone and the nearsighted vision zone. Progressive eyeglasses thus ensure different optical powers in upper and lower portion of each spectacle lens gradually increasing towards the lower periphery. Doctors often recommend progressive glasses to people suffering from presbyopia so that their problem of farsightedness is reduced to a great extent.
