Title (EN) METHOD OF MAKING AN INJECTION MOLDED OPHTHALMIC LENS MOLD AND OF MAKING AN OPHTHALMIC LENS
(FR) PROCÉDÉ DESTINÉ À FABRIQUER UN MOULE POUR LENTILLE OPHTALMIQUE MOULÉE PAR INJECTION ET À FABRIQUER UNE LENTILLE OPHTALMIQUE
Abstract:
(EN) An ophthalmic lens mold comprising a mold half (32, 34) having a front side and a back side, wherein an optical surface (40, 42) on the front side is formed by a film or sheet material and wherein the main body of the mold half is formed by an injection moldable bulk material. The film or sheet material may be provided by over-molded in an injection molding process with the injection moldable bulk material. Also provided is a respective mold assembly comprising the ophthalmic lens mold and a method for making an ophthalmic lens with the ophthalmic lens mold.
(FR) L'invention concerne un moule pour lentille ophtalmique comportant un demi-moule (32, 34) présentant un côté avant et un côté arrière, une surface optique (40, 42) du côté avant étant formée d'un matériau en film ou en feuille et le corps principal du demi-moule étant formé d'un matériau en vrac apte à être moulé par injection. Le matériau en film ou en feuille peut être mis en place par surmoulage lors d'un processus de moulage par injection conjointement avec le matériau en vrac apte à être moulé par injection. L'invention concerne également un ensemble moule correspondant comprenant le moule pour lentille ophtalmique et un procédé de fabrication d'une lentille ophtalmique à l'aide de ce moule pour lentille ophtalmique.
