Title (EN) INTRAOCULAR LENSES HAVING ZONE-BY-ZONE STEP HEIGHT CONTROL
(FR) LENTILLES INTRAOCULAIRES AYANT UNE COMMANDE DE HAUTEUR DE PAS DE ZONE PAR ZONE
Abstract:
(EN) A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2π phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by π. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.
(FR) La présente invention concerne un procédé et un système pour produire un dispositif ophtalmique. Le dispositif ophtalmique comprend une lentille ophtalmique ayant une surface antérieure, une surface postérieure et au moins une structure diffractive comprenant une pluralité de zones. L'au moins une structure de diffraction est pour au moins l'une de la surface antérieure et de la surface postérieure. Chaque zone comprend au moins une échelette ayant au moins une hauteur de pas. La hauteur de pas (s) est individuellement optimisée pour chaque zone. Pour compenser l'aberration chromatique de l'oeil à partir de la distance jusqu'à une plage de vision, une hauteur de pas de phase supérieure à 2π peut être utilisée et la hauteur de pas (s) pliée par une phase, qui est un multiple entier de deux multiplié par pi. Par conséquent, l'aberration chromatique de l'oeil peut être compensée pour améliorer la vision à partir de la distance jusqu'à proximité.
