摘要：
The current invention is directed to a method (100) for determining an eyeglass prescription for an eye, in particular through the use of a non-transitory computer readable medium, the method comprising the steps of providing (110) a measurement Indicative of the refractive properties of the eye； establishing (120) an optimization space corresponding to a plurality of possible eyeglass prescriptions for the eye； determining (140) a merit function, wherein a value of the merit function corresponds to a visual function of the eye when corrected using one of the plurality of possible eyeglass prescriptions within the optimization space, wherein the merit function comprises a term depending on a magnitude of a corrective astigmatism of the one of the plurality of possible eyeglass prescriptions and causing a less optimal value of the merit function the higher the magnitude of the corrective astigmatism and/or the higher the magnitude of a difference between the corrective astigmatism and a subjective corrective astigmatism； and determining (160) the eyeglass prescription by optimizing (150) the value of the merit function, funher, there is suggested 3 system for determining an eyeglass prescription and a corresponding computer program product
