    摘要: A progressive ophthalmic lens including a lens surface having: a lower viewing zone providing good optical quality at a predetermined high surface power over a large area of vision; said predetermined power being determined by the viewer's near prescription (R.sub.x) the horizontal fitting position normally being determined by the near pupillary distance of the wearer, and the vertical fitting position normally being determined by the vertical frame midpoint, an upper viewing zone of lower surface power providing an enhanced range of vision for intermediate or greater viewing distances; and a corridor of relatively low astigmatism extending therebetween; wherein the contours of mean surface power and/or surface astigmatism within the lower viewing zone, upper viewing zone and corridor are generally symmetric about a vertical lens meridian as fitted to the wearer.

    摘要: A series of progressive ophthalmic lens elements, each lens element including a lens surface havingan upper viewing zone having a surface power to achieve a refracting power corresponding to distance vision;a lower viewing zone having a greater surface power than the upper viewing zone to achieve a refracting power corresponding to near vision;a corridor of relatively low surface astigmatism connecting the upper and lower zones, said corridor having a surface power varying from that of the upper viewing zone to that of the lower viewing zone;the progressive ophthalmic lens series includinga first set of lens elements having a base curve(s) suitable for use in providing a range of distance prescriptions for a first category of patient; anda second set of lens elements having a base curve(s) suitable for use in providing a range of distance prescriptions for a second category of patient;each lens element within a set differing in prescribed addition power and including a progressive design, in at least one of the upper and lower viewing zones, depending upon the addition power of the lens element;the lens elements in the first set differing substantively in progressive design from the corresponding lens elements in the second set due to the differences in base curve(s).
