    摘要: What is described here is a method of manufacturing a spectacle lens in which the critical thickness is to be minimized in particular, comprising the following steps of operation: initially, a spectacle lens finished on one side (blank) is manufactured with a predetermined outsides contour and a round outside contour in particular, one part is cut out from the blank, whose outside contour corresponds approximately to the contour of the spectacle lens, the cut-out part is joined with the edge part with an axial offset in such a way that the edge part serves as handle for the subsequent machining operations.

    摘要: Casting a glass major portion of a multifocal lens blank over a glass segment portion of the blank or impressing the segment into the major portion during or immediately after casting. The glass for the major is selected to coincide in viscosity with the segment glass within a range of 105 to 109 poises at least at one temperature, and that above the crossover point the viscosity of the segment glass is higher than the viscosity of the major glass at the same temperature.
