    • In a progressive multifocal ophthalmic lens having an aspherical surface comprising a far vision region (VL), a near vision region (VP), an intermediate vision region, a main meridian of progression passing through these three regions, and a mounting center (CM), the far vision region includes an angular sector with its apex at the mounting center and a central angle of 110°, within which values of sphere and cylinder are less than or equal to 0.50 diopters, and a region of the lens above the near vision reference point and extending substantially up to the middle of the intermediate vision region has a maximum variation in values of cylinder 20 mm to both sides of the meridian limited to less than or equal to 0.30 diopters, and to less than or equal to 10% of the power addition of the lens. The lenses obtained, generally of power addition greater than or equal to 2.50, have wider near and intermediate vision regions, as well as a distribution of sphere and cylinder which is as homogeneous as possible over the complete surface of the lens.

    • A progressive multifocal ophthalmic lens having a far vision region, an intermediate vision region and a near vision region, a main meridian of progression passing through said three regions, and a power addition equal to a difference in mean sphere between a near vision region control point and a far vision region control point is provided. The lens has a progression length less than 12 mm, defined as the vertical distance between a mounting center and a point on the meridian where mean sphere is greater than mean sphere at the far vision control point by 85% of the power addition value. To ensure good visual characteristics not only around the meridian, but also in regions of extra-foveal vision, the ratio between the integral of the product of cylinder times the norm of sphere gradient, on a 40 mm diameter circle centered on the center of the lens, and the product of the area of this circle, power addition and a maximum value of the norm of sphere gradient over that part of the meridian comprised within this circle is less than 0.14.

    • In a multifocal ophthalmic lens comprising an aspherical surface having at every point thereon a mean sphere and a cylinder, a far vision region, a near vision region, and an intermediate vision region, the length of progression i.e. the length over which lens power varies by a set amount in different regions of the lens, is short. To avoid distortion at the periphery of the lens which this would otherwise occasion, the isosphere and isocylinder lines are distributed over the surface of the lens so as to ensure variations in sphere are not too sudden along a 20 mm radius circle centered on the geometric center of the lens and variations in cylinder on the surface of the lens inside this circle are also very small. The lens has an enlarged near vision region and progression is less perceptible to the wearer.
    • 在包括非球面的多焦点眼镜片中,每个点上均具有平均球体和圆柱体,远视区域,近视区域和中间视觉区域,其进程长度即透镜功率变化的长度 在镜片的不同区域设定的量很短。 为了避免透镜外围的变形,否则会出现这种情况,同相和圆柱体线分布在透镜的表面上,以确保球体的变化不会沿着以几何中心为中心的20毫米半径圆 的透镜和该圆周内的透镜表面上的气缸的变化也非常小。 透镜具有放大的近视区域,并且进展对于佩戴者而言较不可察觉。
