Embodiment Construction

[0080] The present disclosure relates to a method implemented by a computer device for determining the degree to which a lens design is suitable for a user.

[0081] Such as figure 1 As shown, the method for determining the degree to which the lens is suitable for the user includes at least:

[0082] - Obtaining a lens design; said lens design represents the variation of optical aberrations as a function of angular viewpoint;

[0083] - obtaining a set of subjective values ​​representing the user's sensitivity to a set of optical aberrations,

[0084] - correlating the set of subjective values ​​with a lens design based on the set of optical aberrations, in order to generate correlation information, advantageously used to determine the degree to which said lens design is suitable for said user from said correlation.

[0085] Each user responds differently to each lens design and expresses a preference for certain types of lens designs. This preference can be assessed by the...

Abstract

The invention provides a method for determining to which extent a lens design is adapted to a user. A method implemented by computer means, the method comprising: obtaining a lens design; the lens design representing the variation of optical aberrations as a function of the angular view point; obtaining a set of subjective values representing the sensitivity of the user to a set of optical aberrations; correlating the set of subjective values and the lens design based on the variation of optical aberrations so as to produce correlation information, advantageously for determining to which extent said lens design is adapted to said user from said correlation.

Description

technical field [0001] The invention relates to a method for determining a user acceptance level of a lens design, a method for determining an optical lens design based on the user acceptance level of a lens design, and a computer program implementing the method steps of the invention. [0002] Additionally, the present invention relates to a device for determining a user's acceptance level of a lens design, a device for determining a lens design most suitable for a wearer, and a device for determining a lens design suitable for a wearer. Background technique [0003] Several recent improvements in the field of ophthalmic lenses have allowed for the provision of customized optical lenses that go beyond the wearer's prescription. When designing ophthalmic lenses, parameters other than the wearer's prescription may be considered, leading to an increase in the number of lens designs. [0004] One of the parameters whose importance is increasingly considered when determining th...
