In the case of a method and an apparatus for manually aligning ophthalmic spectacle lenses (5) , in particular semifinished products of progressive lenses, the spectacle lens (5) is held for the purpose of machining the free side of the spectacle lens (5) by a first holder (6) via a connecting material situated therebetween. The holder (6) is inserted into a cutout of a retaining device (17), the free side being machined. After machining of the free side of the spectacle lens (5), the first holder (6) is inserted into a cutout (2) of an adapter part (10) that is provided with markings (4). Thereafter, the spectacle lens (5) is aligned with the aid of the markings (4) of the adapter part (10), the spectacle lens (5) being held in a second holder (9) via a further connecting material situated therebetween. The second holder (9) is subsequently inserted in the retaining device (17). Finally, the first holder (6) is removed from the spectacle lens (5) together with the adapter part (10) and the connecting material (7) .
L'invention concerne un procédé et un dispositif pour ajuster manuellement des verres (5) de lunettes ophtalmiques, notamment des semi-produits de verres progressifs. Selon l'invention, le verre (5) de lunettes est tenu sur une face par un matériau de liaison intermédiaire d'un premier logement (6) pour permettre le façonnage de la face libre du verre (5) de lunettes, durant lequel ledit logement (6) est placé dans un évidement d'un dispositif de maintien (17). Après le façonnage de la face libre du verre (5) de lunettes, ce premier logement (6) est disposé dans un évidement (2) d'un élément d'adaptation (10) doté de marquages (4) qui servent alors à ajuster le verre (5) de lunettes, lequel (5) est maintenu par un autre matériau de liaison intermédiaire dans un deuxième logement (9). Ce deuxième logement (9) est ensuite placé dans le dispositif de maintien (17). Enfin, le premier logement (6), l'élément d'adaptation (10) et le matériau de liaison (7) sont enlevés du verre (5) de lunettes.
