1. A spectacle lens for a spectacle frame, comprising:
a first spectacle lens area; and
a second spectacle lens area,
wherein the first spectacle lens area is more strongly colored than the second spectacle lens area, and the spectacle lens is integrally phototropic at least in the second spectacle lens area,
wherein a transition area is arranged between the first spectacle lens area and the second spectacle lens area, along which transition area a coloring of the spectacle lens decreases from the first spectacle lens area to the second spectacle lens area,
wherein the coloring changes approximately continuously along the transition area from the color grade of the first spectacle lens area to the color grade of the second spectacle lens area, and
wherein a gradient coloration of the transition area is designed as a function of a refractive power curve in the spectacle lens.
