Abstract
A spectacle lens () has an antireflective coating (). The antireflective coating () produces a residual reflection appearing color-neutral not only under illumination with a natural daylight spectrum, but also under an illumination with an illumination spectrum deviating from the natural daylight spectrum. A method for making a spectacle lens () having an antireflective coating () is described in which an optical lens () is provided and a layer sequence of layers () with alternately high and low refractive material forming the antireflective coating () is applied to the optical lens. The antireflective coating () is applied with the proviso that the antireflective coating () produces a residual reflection appearing color-neutral not only under illumination with a natural daylight spectrum, but also under an illumination with an illumination spectrum deviating from the natural daylight spectrum.
