Title (EN) SPECTACLE LENS WITH ASTIGMATIC EFFECT
(FR) VERRE POUR LUNETTES A EFFET ASTIGMATIQUE
Abstract:
(EN) In order to reduce the critical thickness and/or the variation in the marginal thickness around the periphery of a spectacle lens with astigmatic effect, the refractive index varies at least along the critical main section so that at least a part of the cylindrical effect is achieved by the variation in the refractive index.
(FR) Afin de réduire l'épaisseur critique et/ou la variation de l'épaisseur marginale autour de la circonférence d'un verre pour lunettes à effet astigmatique, l'indice de réfraction varie au moins le long de la section principale critique, de sorte qu'au moins une partie de l'effet de cylindre est assurée par la variation de l'indice de réfraction.
