摘要:
A method for producing an ophthalmic spectacle lens makes it possible to fit out a wearer of lenses in a manner which is customized as a function of a perception of blur by said wearer. The lens (V4) is selected so that the wearer has the impression of having a field of sharp vision which has a reference width. This reference width is determined on the basis of a first lens (V7) which complies with the wearer"s ophthalmic prescription and a reference threshold value of the blur (BR). It is thereafter associated within the lens which is provided for the wearer with a threshold value (B0) of the blur which is perceived by this wearer.
