Abstract

The present invention relates to a spectacle lens comprising an anti-reflective coating, the anti-reflective reflective coating as defined in ISO 13666:2019(E), entry 3.18.3, said anti-reflective coating comprising a plurality of layers, said spectacle lens having, in an interval of angles of incidence, a residual reflectance colour in CIE 1976 L*a*b* colour space, the spectacle lens being characterized in that at an angle of incidence of 0°, positions of CIELAB a*,b* coordinates for said residual reflectance colour lie in a rectangular region in an a*,b* plane, said rectangular region in said a*,b* plane being defined by 2 ≤ a* ≤ 9.2 and 7 ≤ b* ≤ 16.8, in an interval of angles of incidence limited by an angle of incidence of > 0° and an angle of incidence of 75°, each position of CIELAB a*, b* coordinates for said residual reflectance colour, in said a*,b* plane, has a value D ≥ 0, with D = b* + 6.5 · a* + 6.5, the CIELAB a*,b* coordinates are determined with respect to a single surface of said spectacle lens comprising said anti-reflective coating.
