  • Patent number: 11156854
    Abstract: A progressive ophthalmic lens includes at least one multifocal surface, in which at each point of its surface, an astigmatism value and a gradient of astigmatism value can be measured, the lens including: a far-vision zone with a reference point (FV), a near-vision zone with a reference point (NV), an intermediate vision zone with a progression path that connects the far vision zone and the near vision zone, a foveal projection, and a para-foveal projection, and said lens defining a lens addition. When the lens addition is different than 2.00 D, the astigmatism value is k*Add*0.41 D, where Add indicates the lens addition and k is 0.5 and, if the progression path is shorter than 15 mm, the maximum astigmatism value of the foveal projection is (?0.03*d) D/mm+0.86 D, and when the lens progression path is larger than 15 mm, the maximum astigmatism value of the foveal projection is (?0.02*d) D/mm+0.71 D.
