    Abstract: The present invention relates to an optical article comprising a substrate with a front main face and a rear main face, having a colorimetric coefficient b* as defined in the CIE (1976) L*a*b* international colorimetric system that is lower than or equal to 4, a relative light transmission factor in the visible spectrum Tv higher than or equal to 87 %, and blocking at least 8 % of light having a wavelength ranging from 420 to 450 nm arriving on said front main face. This optical article can be used to protect the eyes of a user from phototoxic blue light.

    Abstract: The present invention relates to an optical article comprising a substrate with a front main face and a rear main face, having a colorimetric coefficient b* as defined in the CIE (1976) L*a*b* international colorimetric system that is lower than or equal to 7, a relative light transmission factor in the visible spectrum Tv higher than or equal to 87 %, blocking at least 8 % of light having a wavelength ranging from 420 to 450 nm arriving on said front main face, and having a mean reflection factor Ruv on said rear main face between 280 nm and 380 nm, weighted by the function W(?) defined in the ISO 13666:1998 standard, lower than 7 %, for both an angle of incidence of 30° and for an angle of incidence of 45°. This optical article can be used to protect the eyes of a user from phototoxic blue light and UV light.
