摘要:
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.
