Abstract

A method, implemented by a computer, for determining a lens design of an optical lens adapted to a wearer, the method including: providing a wearer parameter; a lens design determining, during which the lens design of the optical lens adapted to the wearer is determined based at least on the wearer parameters. The wearer parameters include at least optical distortion sensitivity data representative of sensitivity of the wearer to optical distortions.

First claim

The invention claimed is:

1. A method, implemented by a computer, for determining a lens design of an optical lens adapted to a wearer, the method comprising:
determining a lens design for the optical lens adapted to the wearer, based at least on wearer parameters, wherein
the wearer parameters comprise at least optical distortion sensitivity data representative of sensitivity of the wearer to optical distortions due to the optical lens adapted to and newly worn by the wearer.

2. The method according to claim 1 , wherein
each optical distortion sensitivity data is compared to a scale to define an optical distortion sensitivity index.

3. The method according to claim 1 , wherein
the wearer parameters further comprise prescription data and ophthalmic parameters relating to ophthalmic requirements of the wearer.

4. The method according to claim 1 , wherein
the lens design is calculated based at least on the optical distortion sensitivity data.

5. The method according to claim 1 , wherein
the lens design is selected amongst a list of lens designs, the selection being based at least on the optical distortion sensitivity data.

6. The method according to claim 1 , wherein
the lens design comprises at least dioptric lens design.

7. The method according to claim 1 , wherein
the lens design comprises geometrical parameters of the optical lens.

8. The method according to claim 1 , further comprising measuring the optical distortion sensitivity data of the wearer.

9. The method according to claim 8 , wherein
the optical distortion sensitivity data are measured upon a perception test or a discomfort measurement test carried out on the wearer.

10. The method according to claim 8 , wherein
during the optical distortion sensitivity data measurement, optical distortion patterns are presented to the wearer.

11. The method according to claim 10 , wherein
the optical distortion patterns comprise dynamic optical distortion patterns.

12. The method according to claim 8 , wherein
the optical distortion sensitivity data are measured in specific gazing directions.

13. The method according to claim 8 , wherein
the optical distortion sensitivity data are measured in at least a specific part of the field of vision.

14. A method of manufacturing an optical lens adapted for a wearer, comprising:
determining a lens design for the optical lens according to claim 1 ; and
manufacturing the optical lens having the determined lens design.

15. A lens design determining system for determining lens design adapted to a wearer, the system comprising:
a computer processor configured to
receive wearer parameters comprising at least optical distortion sensitivity data representative of sensitivity of the wearer to optical distortions due to the lens adapted to and newly worn by the wearer; and
determine the lens design of the optical lens adapted to the wearer based at least on the wearer parameters.

16. A non-transitory computer readable medium comprising a computer program comprising one or more stored sequences of instructions that are accessible to a processor and which, when executed by the processor, cause the processor to perform:
determining a lens design for an optical lens adapted to a wearer, based at least on wearer parameters, wherein
the wearer parameters comprise at least optical distortion sensitivity data representative of sensitivity of the wearer to optical distortions due to the optical lens adapted to and newly worn by the wearer.
