SPECTACLE LENS AND METHOD OF CALCULATING AND PRODUCING A SPECTACLE LENS

A spectacle lens has an object-side front surface and an eye-side rear surface and is made of a base material that includes an ultraviolet (UV) absorber, which functions as a band-stop filter for UV light. In a first variant, the band-stop filter has an upper cut-off wavelength between 325 nm and 360 with a transmittance of 2% for light which is incident on the front surface, transmitted through the spectacle lens, and emerges from the rear surface for each angle of incidence between 0° and 15°. Additionally or alternatively, in a second variant, the spectacle lens has an antireflective coating with a reflectance below 5% for UV light in a wavelength range between 280 nm and a threshold wavelength, which lies between 325 nm and 350 nm, and a reflectance of 5% at the threshold wavelength for each angle of incidence between 30° and 45°.
