PROBLEM TO BE SOLVED: To provide a progressive-power lens capable of obtaining a proper corrective add diopter corresponding to an apparent adjustment power generated by refractive correction of a wearer, and also to provide the method of manufacturing the same. SOLUTION: This invention relates to a progressive-power lens 100 comprising a farsight portion 101 with a farsight diopter, a nearsight portion 102 with a nearsight diopter, and an intermediate portion 103 in which a refractive power progressively varies in accordance with an add diopter between the farsight portion 101 and the nearsight portion 102. The add diopter is adjustable in accordance with the correction degree of a wearer. COPYRIGHT: (C)2010,JPO&INPIT |
