Abstract

The invention relates to a method for producing a spectacle lens. The method includes the steps of joining together a mould (1) with an integrated block piece (13) and a mould shell (11) produced by primary shaping, and a sealing ring, which has a peripheral seal (21), on a first side an opening for receiving a 10 mould, and on the second side a flexible membrane (22), to form a mould cavity; introducing a polymerizable material into the mould cavity (3) with the aid of a pump action of the flexible membrane (22) of the sealing ring (2); fixing the flexible membrane (22) of the sealing ring (2) in the desired surface 15 shape; carrying out the polymerization; and removing the mould (I), with the cast-on spectacle lens blank, from the sealing ring (2).
