  • Method of making a spectacle lens
    Patent number: 9738040
    Abstract: A method for making a spectacle lens includes joining a mold and a sealing ring. The mold has an integrated block piece and a mold shell made by primary shaping and the sealing ring has a first end face, a second end face, a peripheral seal, an opening disposed on the first end face configured to receive a mold, and a flexible membrane on the second end face. A polymerizable material is introduced into the mold cavity with the aid of a pump action of the flexible membrane of the sealing ring. The flexible membrane of the sealing ring is fixed in a desired surface shape and the polymerization is carried out. The mold is removed with a cast-on spectacle lens blank.
