摘要: The invention relates in particular to a computer-implemented method for calculating or optimising spectacle lens, comprising the following steps: acquiring prescription refraction data A1(x, y) and V A12 of wearer at least two different object distances A1 1 2 ( ≠ ) regarding spherical power Sph v , degree astigmatism Zyl axis Achse ; predetermining an distance model AI(x, y), where AI is (x, denote visual site point lens predetermined predeterminable viewing direction; function P Ref = ƒ (A1), which describes dependence vector, formula (I), on A1; determining components vector plurality sites basis acquired one area taking into account determined y).
