    • A method of determining an ophthalmic prescription (Rx) for a patient's eye, includes obtaining a wavefront measurement of the patient's eye; determining a first Rx for the patient's eye from the wavefront measurement, the first Rx corresponding to a maximum value of a merit function calculated from the wavefront measurement of the patient's eye for a first size of the pupil of the patient's eye; determining one or more additional Rx's of the patient's eye for one or more additional pupil sizes different from the first pupil size, wherein each additional Rx is determined for a corresponding size by calculating a value of the merit function for the previously-calculated Rx at the corresponding size and searching for an Rx at the corresponding size that provides a larger value of the merit function than the previously-calculated Rx at the corresponding size; determining a final Rx based on the first Rx and the additional Rx's; and outputting the final Rx.

    • The invention relates to a method for determining correction characteristics for a vision aid for at least one eye of a person. In order to achieve an individual optimum of vision comfort for the person, the individual physiology of the person is taken into account in the processing of the retina image, in which: in a first step, a vision impression of the person is determined in a first usage condition, in particular by means of a wavefront error measurement and/or a measurement of subjective refraction, after which, in a second step, a vision impression of the person is determined in a second usage condition, in particular by means of a wavefront error measurement, and after which, in a third step, the wavefront of the person is optimized by determining the correction characteristics for the vision aid until the vision impression of the person in the second usage condition at least approximately matches the vision impression of the person in the first usage condition.
