眼鏡用レンズの設計方法、設計装置、及びプログラム

Japanese Patent JP7244824

B2

To provide a spectacle lens design method, design device and program capable of acquiring a spectacle lens that can improve image formation state on a retina by reducing aberration at a retina peripheral part.SOLUTION: A spectacle lens design method comprises: an eyeball model construction step S2 of constructing an eyeball model by determining respective parameter values of a plurality of optical elements; an aberration acquisition step S3 of causing a light beam to enter, with it inclined by a prescribed angle with respect to a visual line of the eyeball model, and acquiring peripheral aberration at a retina peripheral part of the eyeball model by optical simulation; an aspherical surface coefficient value calculation step S4 of placing a spectacle lens in front of the eyeball model to perform the optical simulation and calculating an aspherical surface coefficient value acting in a direction of reducing the peripheral aberration: and an aspherical surface shape determination step S5 of determining an aspherical surface shape of the spectacle lens on the basis of the aspherical surface coefficient value.SELECTED DRAWING: Figure 2
