Zusammenfassung: | Provided is spectacle lens related to a wearer. The spectacle lens has a refractive power and at least partly a diffractive add power and provides a central region having a first diffractive add power and being adjusted for emmetropia of the wearer. The spectacle lens further provides a peripheral region arranged radially outside of the central region, wherein the peripheral region has a second diffractive add power and is adjusted to provide a focus in at least one of in front of the retina of the wearer or behind the retina of the wearer. The spectacle lens design data is adjusted such that the spectacle lens further exhibits a first blending region arranged between the central region and the peripheral region, wherein the first blending region is adapted to adjust a diffraction efficiency from the first diffractive add power to the second diffractive add power in a radially outward direction. |
