Abstract

See full text

A spectacle lens having a front surface intended to be fitted away from the eye. The spectacle lens includes a substrate made from mineral glass or an organic material. The spectacle lens has selective light wavelength filter properties. The selective light wavelength filter properties include a spectral transmittance between 80% and 95% for all wavelengths in a wavelength range between 428 nm and 452 nm for a light ray entering the spectacle lens on the front surface at an angle of incidence of 0°, a spectral transmittance between 95% and 100% for all wavelengths in a wavelength range between 500 nm and 700 nm for a light ray entering the spectacle lens on the front surface with an angle of incidence of 0° and a yellowness index of no more than 10 for a standard illuminant D65 and a standard observer function of 2° (D65/2°).
