Claim 24:
25. The product as claimed in claim 15, further comprising:
(i) a representation, stored on the non-transitory data medium as the computer-readable data, of a predetermined arrangement of the progressive power spectacle lens in front of an eye of a progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, or (ii) the non-transitory data medium having computer-readable data concerning a predetermined arrangement of the progressive power spectacle lens in front of an eye of a progressive power spectacle wearer,
wherein the progressive power spectacle lens has a distribution of a spherical equivalent for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended,
wherein the product further includes:
(i) a representation, stored on the non-transitory data medium as the computer-readable data, of a residual astigmatism distribution for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(ii) a representation, stored on the non-transitory data medium as the computer-readable data, of an astigmatic power distribution, required for a full correction, for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(iii) a representation, stored on the non-transitory data medium as the computer-readable data, of a prescription and an object distance model for the predetermined arrangement of the progressive power spectacle lens in front of the eye of a progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(iv) a representation, stored on the non-transitory data medium as the computer-readable data, of a distribution of the spherical equivalent for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(v) the non-transitory data medium having computer-readable data concerning a residual astigmatism distribution for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(vi) the non-transitory data medium having computer-readable data concerning an astigmatic power distribution, required for a full correction, for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(vii) the non-transitory data medium having computer-readable data concerning a prescription and an object distance model for the predetermined arrangement of the progressive power spectacle lens in front of the eye of a progressive power spectacle wearer, for whom the progressive power spectacle lens is intended, and/or
(viii) the non-transitory data medium having computer-readable data concerning a distribution of the spherical equivalent for the predetermined arrangement of the progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, for whom the progressive power spectacle lens is intended,
wherein the refractive index of the progressive power spectacle lens varies in space such that the maximum value of the residual astigmatism of the progressive power spectacle lens is less than the maximum value of the residual astigmatism of a comparison progressive power spectacle lens with a same distribution of the spherical equivalent in the case of a same arrangement of the comparison progressive power spectacle lens in front of the eye of the progressive power spectacle wearer, but with a spatially non-varying refractive index.
