摘要： A multifocal ophthalmic lens comprising a far vision region, a near vision region and an intermediate vision region is provided having a high near vision region and a wide vision field in the near vision region, the intermediate vision region and in the far vision region. Progression is gentle although the distance between a mounting center on the lens and the point where power addition is 85% higher than power addition at a far vision control point is less than 16 mm, while simultaneously maximum cylinder inside a 20 mm radius circle centered on a geometrical center of the lens is kept at a low value.

摘要： 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.
