Title
(EN) MOLDS AND METHOD OF USING THE SAME FOR OPTICAL LENSES
(FR) MOULES ET PROCEDE D'UTILISATION DE CEUX-CI POUR DES LENTILLES OPTIQUES
Abstract
(EN) The present invention encompasses, in part, a method and apparatus for lens casting in which two molds (20 and 40), preferably formed of plastic, are interconnected or joined together via a ring (50) to form a mold cavity (60) having substantially the same dimensions of the lens to be formed therein. The invention is further directed to compositions and methods used in lens casting. In a first implementation the invention includes a mold (10) having a ring (50) having an interior periphery (54), a front mold (20) formed of a plastic and having a lens-forming surface (22), an edge (28) circumscribing the lens-forming surface that is sized to be complementarily received within a portion of the interior periphery of the ring, and a base (30) having dimensions greater than the interior periphery, and a rear mold (40) formed of a plastic having a lens-forming surface (42).
(FR) L'invention concerne, en partie, un procédé et un appareil permettant de mouler des lentilles et dans lesquels deux moules, de préférence en plastique, sont interconnectés ou assemblés par le biais d'un anneau, de manière à former une cavité présentant sensiblement les mêmes dimensions que les lentilles à former dans ceux-ci. L'invention concerne également des compositions et des procédés utilisés dans le moulage de lentilles. Dans un premier mode de réalisation, l'appareil comprend un moule présentant un anneau doté d'une périphérie intérieure; un moule avant formé dans un plastique et comprenant une surface de formation de lentille, un bord entourant ladite surface et dimensionné de manière à être reçu de façon complémentaire dans une partie de la périphérie intérieure de l'anneau et une base présentant des dimensions supérieures à celles de la périphérie intérieure; ainsi qu'un moule arrière formé dans un plastique et possédant une surface de formation de lentille.
