    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 calculating an individual progressive lens creates one or more basic designs for lenses based on theoretical specifications, and then creates starting designs from these basic designs. Individual progressive lenses are calculated from the starting designs corresponding to the individual data from wearing test subjects. Valid starting designs are then created fr production. The individual lenses are calculated from the starting designs according to individual customer data.

      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.
