    摘要: An ophthalmic lens and a method for producing a progressive ophthalmic lens having at least one progressive surface, where by a calculation and optimization step in the production of the progressive lens is performed. The absolute value of the rotation |rot {right arrow over (A)}| and/or the divergence |div {right arrow over (A)}| of a vectorial astigmatism {right arrow over (A)} is as small as possible, and the absolute value |{right arrow over (A)}| of the vectorial astigmatism {right arrow over (A)} is proportional to the absolute value of an astigmatism in the use position of the progressive lens. The direction of the vectorial astigmatism {right arrow over (A)} is proportional to the axial position of an astigmatism in the use position of the progressive lens or a surface astigmatism of the at least one progressive surface 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 spectacle lens comprises a region (distance portion) designed for viewing at large distances and in particular “to infinity”; a region (near portion) designed for viewing at short distances and in particular “reading distances”; and a progressive zone disposed between the distance portion and the near portion, in which a power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at a near reference point located in the near portion along a curve (principal line) veering towards a nose. The invention is distinct in that, for minimizing a change of binocular imaging properties with horizontal movements of glance, a lift (difference between a maximum and a minimum value occurring during a movement) of binocular imaging properties when a moving object is being followed, is smaller than a physiologically pre-determined limiting amount.

    摘要: A method and apparatus for creating a progressive spectacle lens design by transforming a starting design. The starting design is defined to include specifications for the course of a principal line and specification of at least one base target isoastigmatism line with a constant base target astigmatism, in which the base target isoastigmatism line passes through a first predetermined control point {right arrow over (r)}1=(u1,y1). The method and apparatus transform the starting design by shifting the first control point {right arrow over (r)}1=(u1,y1) along a predetermined or predeterminable curve, taking into account the design and/or the spectacle lens wearer-specific data; modifying the course of the base target isoastigmatism line such that it passes through the shifted first control point {right arrow over (r)}′1(u′1,y′1); and calculating a target astigmatism distribution A(u,y), which exhibits the modified base target isoastigmatism line. Furthermore, the method and apparatus are provided to create the spectacle lens on the basis of the progressive spectacle lens design.

    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.
