    摘要: A double progressive spectacle lens in which a first prescribed progressive surface can be freely designed. The second progressive surface is then optimized in relation to the first prescribed surface. Thereby, the resulting spectacle lens avoids the need to employ a classic hourglass design progression zone and produces optical and geometric advantages such as an overall height of the progressive lens.

      摘要: A method of optimizing a progressive lens is described. This invention is characterized by the following steps: selecting a preset progressive lens having a preset object distance function A1(x,y), selecting an object distance function A2(x=x0,y) along the main line of vision of the preset progressive lens for a lens that is to be derived, locating the map U:y→y′ along the main line of vision, such that the value y′ for which the following holds is calculated for each value of y: A1(x=x0,y)=A2(x=x0,y′), calculating the setpoint values S(x,y) at S(x,y′)=S(x,U(y)).

      摘要: A workplace screen lens, having a workplace screen lens optimized at the middle of the lens for the middle viewing distances of approximately 60 centimeters to approximately 90 centimeters, and the progressive channel at the middle of the lens is at least 4 millimeters wide. The effect increases from the middle of the lens toward the bottom with the vertical coordinate y equal to approximately 0, reaching a near vision zone with an essentially constant effect at y equal to approximately −12 millimeters. The progressive channel has a width of least 15 millimeters in the near vision zone, preferably at the near-reference point, the effect decreases from the middle of the lens up to y equal to approximately +10 millimeters to approximately +12 millimeters above the middle of the lens. The progressive length amounts to approximately 20 millimeters to approximately 25 millimeters, the main progressive length is between approximately 7 millimeters and approximately 12 millimeters, and the minimum width of the progressive channel amounts to at least 4 millimeters.
