PROGRESSIVE REFRACTIVE POWER LENS AND DESIGNING SYSTEM THEREOF

PROBLEM TO BE SOLVED: To provide a progressive refractive power lens, that hardly causes inconvenience of a wearer even when designing a new progressive refractive power lens based on a design of progressive refractive power lenses of different kinds, and a design system of the progressive refractive power lens.SOLUTION: A progressive inner surface shape is formed so that |HF1|>|HF2'|, in which HF1 denotes a height from the optical axis of the progressive refractive power lens to a distance portion reference point being set in an outer surface in a direction perpendicular to the optical axis, and HF2' denotes a height from the optical axis of the progressive refractive power lens to a point where a transmission light beam passing through the distance portion reference point intersects an inner surface in the direction perpendicular to the optical axis.
