A method for determining an optical system of a personalized progressive lens for a given wearer is revealed, comprising the following consecutive steps: a) providing a mean direction of gaze determined for the wearer in a reference frame tied to the head of the said wearer; b) determination of a target value for at least one optical design parameter as a function of the mean direction of gaze determined in step a); and c) calculation of the optical system of the progressive lens by an optical optimization procedure on the basis of target values where the target value of the (or of each) optical design parameter as a function of the mean direction of gaze determined in step b) is a target value. 披露了种用于确定给定配戴者的个性化渐变镜片的光学系统的方法，所述方法包括以下连续步骤：a)提供在与所述配戴者的头部相关的参考系中针对所述配戴者确定的平均注视方向；b)根据在步骤a)中确定的所述平均注视方向来确定至少个光学设计参数的目标值；c)基于目标值通过光学优化环节来计算所述渐变镜片的光学系统，其中，在步骤b)确定的随所述平均注视方向而变的所述或每个光学设计参数的目标值是目标值。
