| titleOfInvention | bluish-looking optical material that cuts blue light |
| abstract | the present invention relates to an optical material that cuts blue light, comprising at least one UV absorber that at least partially blocks light with a wavelength ranging from 400 to 450 nm, at least one absorbent dye with its maximum absorption wavelength in the range of 520 nm to 640 nm, the optical material being made of a material chosen from polythiurethane materials, urea polyurethane materials, materials resulting from the polymerization or copolymerization of monomers or polysulfide oligomers, and resulting materials of polymerization or copolymerization of allyl monomers or oligomers, the optical material having a colorimetric coefficient b * as defined in the international colorimetric system cie (1976) l * a * b * which is less than or equal to 6 and a hue angle greater or equal to 120 ° and less than or equal to 180 °, for an optical material thickness of 2 mm. |
