    Abstract: The invention relates to a lens with a horizontal prismatic refractive power which varies progressively along the principal meridian of progression (MM') with an addition of horizontal prismatic power greater than 2 prismatic dioptres in absolute terms. This addition of horizontal prismatic power is defined by the difference in power of horizontal prismatic refraction at a reference point (L) in the distant field of vision and the power of horizontal prismatic refraction at the point (P') of projection of the point of reference (P) in the near field of vision (VP) onto the vertical passing through the point of reference (L) of the distant field of vision.

    Abstract translation: 本发明涉及一种具有水平棱镜折射光焦度的透镜,其沿着主子午线(MM')逐渐变化,并且以绝对项增加大于2棱镜透镜的水平棱镜光焦度。 这种水平棱镜光焦度的增加由远视场中参考点(L)处的水平棱镜折射光焦度的差异和光点的投影点(P')处的水平棱镜折射光焦度的定义 将近视场(VP)中的参考点(P)引导到通过远视场的参考点(L)的垂直线上。

    Abstract: The lens presents horizontal prismatic refractive power that varies progressively along the main progression meridian (MM') with the addition of horizontal prismatic power being greater than 2 prismatic diopters in absolute value, this addition of horizontal prismatic power being defined by the difference between the horizontal prismatic refractive power at the reference point (L) of the far vision zone and the horizontal prismatic refractive power at the projection point (P') of the reference point (P) of the near vision zone (VP) on the vertical line passing through the reference point (L) of the far vision zone.
