摘要

A computer implemented optimizing a progressive spectacle lens comprising the steps of method: specifying a distance function initial object A1G (y), obtaining distance data object where the data object distance comprise a object distance in at least one given point on the principal sight line; modification of the distance function to the initial object based on data obtained object distance; optimization of the progressive spectacle lens, where the optimization of the spectacle lens is taken into account the distance function modified object, wherein the modification of the distance function initial object A1G (y) comprises an A1 overlap (y) = A1G (y) + A1Korr (y) of the distance function initial object A1G (y) with a correction function A1Korr (y), where the correction function has at least one variable parameter which it is determined data object distance obtained so that the value of the distance function initial object modified in at least one given point is equal to the reciprocal of the distance from the initial object obtained, and where the function of object distance is defined as the reciprocal object distance along the principal sight line and y is the vertical coordinate, where the correction function is a double asymptotic function with parameters akorr, bkorr , Ckorr, dkorr, mkorr where bkorr and akorr function correction parameters are determined depending on the distance to the object data obtained; or where the correction function is a linear function of the distance function AKorr initial object (y) = c + mA1G (y) with the parameters c and m.
