Title (EN) COATED LENS TO REDUCE VISUAL PERCEPTION OF STAINS
(FR) LENTILLE PORTANT UN REVETEMENT DE FAÇON A REDUIRE LA PERCEPTION DES TACHES
Abstract:
(EN) A coated optical lens includes a lens element and a stain masking coating on a surface of the lens element. The coating does not substantially vary in colour when stained by contaminants (e.g. body oils) having a refractive index in the range of approximately 1.3 to 1.6. The coating has multiple layers. The thickness and/or number of the layers are selected to reduce the visibility of stains. The coating functions as an anti-reflective or reflective (mirror) coating. Specific coatings may be designed with appropriate coating design software.
(FR) L'invention concerne une lentille optique portant un revêtement, comprenant un élément de lentille, et un revêtement masquant les tâches sur une surface de l'élément de lentille, lequel revêtement ne change sensiblement pas de couleur lorsqu'il est taché par des contaminants présentant un indice de réfraction situé dans la plage d'environ 1,3 à 1,6. Ce revêtement est un revêtement multicouche dont l'épaisseur et/ou le nombre sont sélectionnés, afin de réduire la visibilité des tâches. L'invention concerne également des fonctions de revêtement (miroir) réfléchissant ou anti-réfléchissant.
