INNER FACE PROGRESSIVE REFRACTIVE POWER LENS, METHOD FOR DESIGNING INNER FACE PROGRESSIVE REFRACTIVE POWER LENS, AND METHOD FOR MANUFACTURING INNER FACE PROGRESSIVE REFRACTIVE POWER LENS

摘要

PROBLEM TO BE SOLVED: To obtain an inner face progressive refractive power lens, in which a diopter, an addition power, and a corridor length can be defined and measured in the same procedures as for an outer face progression, and optical performances are stably and favorably maintained.;SOLUTION: The inner face progressive refractive power lens includes an outer face as a non-progressive face and an inner face as a progressive face. The inner face progressive refractive power lens is designed in such a manner that: a reference point for diopter measurement is set on the outer face as a non-progressive face; a progressive zone length designated by a prescription value is achieved on the outer face; and the inner face as a progressive face can achieve an addition effect equal to that of an outer face progressive refractive power lens having the progressive zone length and an addition power designated by the prescription values on the basis of the reference point for diopter measurement, in a wearing state where a beam passing through the inner face progressive refractive power lens passes a rotation point of an eyeball.;COPYRIGHT: (C)2015,JPO&INPIT
