Abstract

Adjustment of an eyeglass lens or a pair of eyeglasses by means of an individual brightness-dependent centering of an eyeglass lens. In particular, a method for adjusting an individual eyeglass lens for at least one eye of an eyeglass wearer, including: defining an individual usage situation which comprises at least one target brightness value for the light to be captured by the at least one eye; determining a position of the pupil in at least one direction of view of the at least one eye which occurs or is expected at the at least one target brightness value; determining a reference point of the eyeglass lens, in which the eyeglass lens effects a required correction of individual refraction data for the at least one direction of view; on the basis of the determined individual value of the pupil position, providing and arranging the eyeglass lens in such a manner that the at least one reference point of the eyeglass lens is arranged in front of the at least one eye of the eyeglass wearer.

First claim

The invention claimed is:

1. A method for calculating an individual spectacle lens for at least one eye of a spectacle wearer, comprising:
providing a distribution of eye data, which comprise at least higher-order aberrations, for a plurality of eyes, and one physical or physiological parameter;
determining a value of the at least one physical or physiological parameter for the at least one eye of the spectacle wearer;
determining the most probable values, according to the provided distribution of eye data, for the higher-order aberrations of the at least one eye of the spectacle wearer for the determined value of the at least one physical or physiological parameter for the at least one eye;
calculating one or more surfaces of the spectacle lens such that the spectacle lens corrects an effect of higher-order aberrations according to the determined most probable values at least partly; and
manufacturing the spectacle lens in accordance with the calculated one or more surfaces to correct the effect of the higher-order aberrations for the at least one eye of the spectacle wearer.

2. The method of claim 1 , wherein providing the distribution of eye data comprises providing a distribution of higher-order aberrations of a plurality of eyes, which depend on refraction data, and
wherein determining the at least one physical or physiological data for the at least one eye of the spectacle wearer comprises determining refraction data of the at least one eye.

3. The method of claim 1 , wherein providing the distribution of eye data comprises providing a distribution of higher-order aberrations of a plurality of eyes, which depend on pupil data, and
wherein determining the at least one physical or physiological data for the at least one eye of the spectacle wearer comprises determining pupil data of the at least one eye.

4. The method of claim 1 , wherein providing the distribution of eye data comprises providing a distribution of higher-order aberrations of a plurality of eyes, which depend on an age, and
wherein determining the at least one physical or physiological data for the at least one eye of the spectacle wearer comprises determining the age of the spectacle wearer.

5. The method of claim 1 , wherein providing the distribution of eye data comprises providing a distribution of higher-order aberrations of a plurality of eyes, which depend on brightness, and
wherein determining the at least one physical or physiological data for the at least one eye of the spectacle wearer comprises determining an individual situation of wear, which comprises at least one brightness target value for the light to be captured by the at least one eye.

6. The method of claim 1 , further comprising:
providing the most probable pupil data, including a pupil size or a pupil position, of the at least one eye for at least one brightness; and
calculating the one or more surfaces of the spectacle lens such that it corrects the effect of higher-order aberrations according to the determined most probable values, including the most probable pupil data, at least partly.

7. The method of claim 6 , wherein providing the most probable pupil data comprises:
providing a distribution of pupil data for a plurality of eyes depending on the brightness and at least one further physical or physiological parameter;
determining a value of the at least one further physical or physiological parameter for the at least one eye of the spectacle wearer; and
determining the most probable values, according to the provided distribution of pupil data, for the pupil data of the at least one eye of the spectacle wearer depending on the brightness for the determined value of the at least one further physical and/or physiological parameter for the at least one eye.

8. The method of claim 7 , where the at least one further physical or physiological parameter comprises refraction data.

9. The method of claim 1 , wherein the distribution of eye data does not include data associated with the at least one eye of the spectacle wearer.

10. The method of claim 1 , wherein the one or more surfaces of the spectacle lens are calculated without using data associated with higher-order aberrations for the at least one eye of the spectacle wearer.

11. The method of claim 1 , wherein the manufactured spectacle lens corrects the effect of the higher-order aberrations for the at least one eye of the spectacle wearer from a plurality of directions of sight.
