Abstract: The invention concerns a set of progressive multifocal opthalmic lenses, each having a first progressive multifocal surface and a second surface preferably spherical. It proposes to define the set of lenses with regard to the optical characteristics of the lenses, and particularly wearer power and oblique astigmatism, in worn conditions. For this purpose, the invention defines an ergorama associating with each sight direction in worn conditions a target object point, and a given power. This ergorama supplies a power target for a definition by optimisation of the lenses, and is used in a radii plotting programme for calculating the optical characteristics during optimisation. The set of lenses has substantially identical optical performances for a given addition, whatever the power of the far vision reference point.

Abstract: In a pair of progressive multifocal ophthalmic lenses, in which each lens has an aspherical surface comprising a far vision portion, a near vision portion, an intermediate vision portion, and a prime meridian of power progression passing through these three portions, the prime meridians of progression of the lenses are substantially symmetrical with respect to each other, and one of the lenses is more particularly dedicated to far vision and the other is more particularly dedicated to near vision, the lens dedicated to far vision having a more extensive far vision portion than the far vision portion of the lens dedicated to near vision, and the lens dedicated to far vision having a less extensive near vision portion than the near vision portion of the lens dedicated to near vision.
