Lens Design Method, Lens Manufacturing Method, Storage Medium, And Lens Design System

摘要

A lens design method includes: changing curve data including a curve value of a distance vision part and a curve value of a near vision part of a progressive power lens on an object side and a curve value of a distance vision part and a curve value of a near vision part of the progressive power lens on an eyeball side so as to be suited to prescription values to calculate a plurality of sets of the curve data; and calculating, for each of the calculated sets of the curve data, a thickness at a second position on the progressive power lens that satisfies thickness conditions for a first position on the progressive power lens.

1. A lens design method comprising;
changing curve data including a curve value of a distance vision part and a curve value of a near vision part of a progressive power lens on an object side and a curve value of a distance vision part and a curve value of a near vision part of the progressive power lens on an eyeball side under conditions suited to prescription values to calculate a plurality of sets of the curve data; and calculating, for each of the calculated sets of the curve data, a thickness at a second position on the progressive power lens that satisfies thickness conditions for a first position on the progressive power lens.
