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.

Lens design method, lens manufacturing method, storage medium, and lens design system

A lens processing management system includes a lens processing section that processes a lens based on design data, an authentication section that is substantially attached to a lens material or a semi-finished lens product, and an authentication processing section that performs an authentication process for the processing of the lens using the authentication section.
