Abstract:
The invention relates to a method for computer-assisted evaluation of the performance of progressive lenses, specifically while taking into account individual parameters of a given eyeglass wearer, the individual parameters including at least personal prescription data, in particular, additional spherical, astigmatic, and/or prismatic power, and/or personal wearer data for the eyeglass wearer, in particular, forward inclination, horizontal frame inclination, corneal vertex distance, and/or interpupillary distance. The method includes the following steps: determining the individual parameters; calculating a total performance factor P in each case for at least two quality classes of progressive lenses as a function of the individual parameters, the total performance factor P being correlated with the quality of the monocular visual acuity and/or binocular visual impression; and outputting the calculated total performance factor P for the quality classes.
