Progressive lenses, also called progressive addition lenses (PAL), progressive power lenses, graduated lenses, and varifocal lenses, are corrective lenses used in eyeglasses to correct presbyopia and other disorders of accommodation. The wearer can adjust the additional lens power required for clear vision at different viewing distances by tilting his or her head to sight through the appropriate part of the vertical progression. T
