Abstract
A spectacle lens is disclosed that includes a lens substrate and a coating that is applied onto the lens substrate. The coating has a first reflectivity of at least 20% for near infrared light at a first wavelength λ, which impinges on the coating at an angle of incidence of 0°, and a second reflectivity for near infrared light at the first wavelength λ, which impinges on the coating at an angle of incidence of 35°, the second reflectivity being reduced by at least 10% in relation to the first reflectivity. The present disclosure further relates to a computer-implemented or experimental method for designing such a spectacle lens and a corresponding method for producing a spectacle lens.
