| description | A method for designing an eyeglass lens includes an eyeball model construction step of determining a value of a parameter of each of a plurality of optical elements, and constructing an eyeball model, an aberration acquisition step of making a light ray incident at a predetermined angle with respect to a visual axis of the eyeball model to obtain an off-axis aberration in a paracentral portion and a peripheral portion of a retina of the eyeball model by an optical simulation, an aspherical coefficient value calculation step of disposing an eyeglass lens on a front side of the eyeball model and performing the optical simulation to obtain an aspherical coefficient value acting in a direction of reducing the off-axis aberration, and an aspherical shape determination step of determining an aspherical shape of the eyeglass lens based on the aspherical coefficient value. |
