The invention relates to a method for producing a multilayer lens which is made of plastic by molding in an injection device a plurality of intermediate layers of a plastic material one by one onto a base part (20) in different cavities (23, 24, 25, 26, 27), at least one of the cavities (23, 24, 25, 26) having a first gating system (33) with a common material feed (35). A second gating system (34) is used to mold at least one outer layer made of a plastic material in an additional cavity (27), said second gating system having its own material feed and its own control unit. |
