| description | 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
【課題】網膜周辺部での収差を低減して、網膜上での結像状態を改善させることが可能な眼鏡用レンズを得ることができる眼鏡用レンズの設計方法、設計装置、及びプログラムを提供する。【解決手段】眼鏡用レンズの設計方法は、複数の光学要素それぞれのパラメータの値を決定して眼球モデルを構築する眼球モデル構築ステップＳ２と、前記眼球モデルの視軸に対し所定角度傾けて光線を入射させ、当該眼球モデルの網膜周辺部での周辺収差を光学シミュレーションにより求める収差取得ステップＳ３と、前記眼球モデルの前方に眼鏡用レンズを配置して前記光学シミュレーションを行い、前記周辺収差を低減させる方向に作用する非球面係数値を求める非球面係数値算出ステップＳ４と、前記非球面係数値に基づいて、前記眼鏡用レンズの非球面形状を決定する非球面形状決定ステップＳ５と、を有する。【選択図】図２ |
