Zusammenfassung: | The present invention relates to a method for manufacturing a spectacle lens, the method comprising: capturing data regarding a surface to be produced of the spectacle lens to be manufactured; providing a first casting mold for the spectacle lens to be manufactured, wherein the first casting mold has a first casting mold surface, the shape of which is determined on the basis of the data regarding the surface to be produced of the spectacle lens; and shaping the spectacle lens from a curable spectacle-lens material using the first casting mold. The step of providing the first casting mold comprises: determining the shape of an adaptive surface using the data regarding the surface to be produced of the spectacle lens; producing the adaptive surface having the determined shape by means of a surface-shaping device; and using the adaptive surface for producing the first casting mold surface. The step shaping the spectacle lens comprises curing the spectacle-lens material, wherein, during the curing process, the surface-shaping device is separated from the first casting mold. The present invention also relates to a device for manufacturing a spectacle lens, which device is designed to carry out the above method. |
