A method for making relief for a progressive ophthalmic lens and associated progressive ophthalmic lens (n).

摘要

It is a progressive ophthalmic lens, the front face (11a), for example, comprises, in a continuous manner, on the one hand, a central zone (14), which, having a progressively varying curvature along at least a portion of at least a meridian, as is the optically active area, and, on the other hand, around this central zone (14), a peripheral zone of connection (15) is connected tangentially to the -. & br / according to the invention, the optically active central area (14) of this front face (11a) is delimited by a closed curve, which, in projection on a plane perpenculaire to the geometrical axis of the assembly, is generally oval in shape, and the radius of curvature of the radial section of its peripheral zone of connection (15) varies circumferentially in value and / or sign, so that, along its peripheral edge (13), the lens is generally equivalent -. & br / application to the obtaining of progressive ophthalmic lenses are easier to produce more aesthetic and lighter.
