Claim 23:
24. The product as claimed in claim 22, further comprising:
(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 the 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 the 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 the 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 the 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 progressive power spectacle lens has a distance portion and a near portion, and
wherein the width of the intermediate corridor corresponds to the dimension transverse to a longitudinal direction of the intermediate corridor extending between the distance portion and near portion, within which the absolute value of the residual astigmatism lies below a predetermined limit value, which is selected within a range from the group specified below:
(a) the limit value lies in the range between 0.25 dpt and 1.5 dpt,
(b) the limit value lies in the range between 0.25 dpt and 1.0 dpt,
(c) the limit value lies in the range between 0.25 dpt and 0.75 dpt,
(d) the limit value lies in the range between 0.25 dpt and 0.6 dpt,
(e) the limit value lies in the range between 0.25 dpt and 0.5 dpt,
(f) the limit value is 0.5 dpt.
