The method involves determining the average curvature of the cornea (16) of an eye (10), and determining the average phase error of the eye. The method involves determining the eye length (LA) from the average curvature and the average phase error, and determining the location of the eye fulcrum (ADL) from the eye length. Independent claims are included for the following: (1) a method for optimizing an individual eyeglass lens for an eye of a test subject (2) a method for determining two optical parameters of eye having a reference structure (3) a computer program with a program code provided for the execution of the method (4) a device to the determination of eye fulcrum in eye of a test subject and (5) a device for determining two optical parameters of eye having a reference structure.本発明は、被検者の眼(10)の眼球支点位置(ADL)を決定する方法に関する。該方法は、a)眼(10)の角膜(16)の平均曲率(KH)を決定するステップ、b)眼(10)の平均位相誤差(PF)を決定するステップ、c)平均曲率(KH)と平均位相誤差(PF)から眼軸長(LA)を決定するステップ、d)眼軸長(LA)から眼球支点位置(ADL)を決定するステップを含む。【選択図】 図2
