    摘要: What is described here is a method of manufacturing progressive ophthalmic lenses whereof each is produced in correspondence with the individual data of a specific spectacle wearer, and whereof each presents a first surface having a defined surface power value in the surface apex, and presents a non-spherical second surface (prescription surface) whose surface power varies along a line (referred to as principal line in the following) that follows at least approximately the main line of sight when the view is lowered, such that the ophthalmic lens produces a first effect in a first reference point, which is suitable for viewing in a first distance envisaged for the respective application, and that this effect varies along the principal line by a predetermined value (addition Add) to a second value present in a second reference point, which is suitable for viewing in a second distance envisaged for the respective application, and whose second surface possibly presents a surface astigmatism optionally for partly compensating an ocular astigmatism and/or the astigmatism of oblique bundles. The inventive method excels itself by the following steps of operation: initially, ophthalmic lens blanks (blanks) are produced with a finished first surface in a defined—particularly comparatively narrow—grading of the surface power value, starting out from the individual data, specifically at least the respective required first effect Df the addition Add and possibly the value and the axial position of the ocular astigmatism of the spectacle wearer for whom the respective ophthalmic lens is intended, and on the basis of further design data, a first surface with a defined surface power value D, is selected and the second surface is so computed that the surface power value D2f of the second surface, which is required in the first reference point, is adjusted in correspondence with the respective selected surface power D, of the first surface so that, as a function of the respective design data for one and the same first effect D, and one and the same addition Add and possibly also one and the same value and axial position of the ocular astigmatism, different pairings of first surfaces, which are distinguished from each other at least with respect to the surface power value D1 and of associated second surfaces computed on an individualized basis in each case are achieved.

    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 for production. The individual lenses are calculated from the starting designs according to individual customer data.
