Title:
EYEGLASS LENS DESIGN DEVICE, EYEGLASS LENS DESIGN METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/163151
Kind Code:
A1
Abstract:
An eyeglass lens design device for designing a pair of aspherical lenses which exhibit rotational symmetry or axial symmetry around a component of a fixed focal length lens for a distance prescription comprising a fixed focal length lens or progressive refractive lens and having different strengths for the left and right lenses, said eyeglass lens design device being equipped with: an acquisition unit for acquiring left prism amount information which corresponds to the left-eye strength and right prism amount information which corresponds to the right-eye strength; a calculation unit for calculating a computed value of the left prism amount and right prism amount on the basis of the left prism amount information and the right prism amount information; and a change unit for calculating a design parameter change amount in the right-eye aspherical lens and/or the left-eye aspherical lens on the basis of the computed value of the left prism amount and right prism amount, and changing the design parameter on the basis of the calculated design parameter change amount.
