Abstract

The present invention relates in summary to a method for checking and/or determining user data of a spectacle lens user comprising providing subjective data of a spectacle lens user, wherein the subjective data comprise at least subjective refraction data, providing objective refraction data of the spectacle lens user, comparing at least one subset of the subjective refraction data with at least one subset of the objective refraction data and determining a comparison result, matching at least the subset of the subjective refraction data to the objective refraction data on the basis of the comparison result under the assumption that the comparison result fulfills at least one predetermined comparison condition, otherwise maintaining at least the subset of the subjective refraction data and/or providing a message containing the comparison result, and to a further method, a computer program product and two devices for checking and/or determining user data.

Dependent claims

A method for at least one of checking and determining user data of a spectacle lens user, comprising using a microprocessor to perform the following:

providing subjective data of a spectacle lens user, wherein the subjective data including at least subjective refraction data;
providing objective refraction data of the spectacle lens user;
comparing at least a subset of the subjective refraction data with at least a subset of the objective refraction data, and determining a comparative result;
and
changing one or more values of the subjective refraction data so that at least the subset of the subjective refraction data matches the objective refraction data on the basis of the comparative result provided that the comparative result fulfills at least one predetermined comparative condition, and otherwise, at least one of maintaining at least the subset of the subjective refraction data and providing a message containing the comparative result, wherein at least two of the subjective refraction data, the matched subjective refraction data and the objective refraction data are combined to form combined refraction data, and wherein the combined refraction data designated as PK are calculated by addition of the objective refraction data designated as Pobj with the subjective refraction data designated as Psub as follows:
PK=GobjPobj+GsubPsub
