Abstract
El molde para lente oftálmico incluye una primera mitad de molde que tiene un lado frontal y un lado posterior. El lado frontal define una superficieoptica. Después de alinear la primera mitad del molde con respecto a la segunda mitad del molde, de tal manera que los lados frontales queden opuestos uno alotro, se forma una cavidad de molde entre los lados frontales para formar un lente oftálmico en la misma, a partir de un material moldeable. La primera mitaddel molde incluye una primera seccionque transmite luz de curado, y que se extiende desde el lado posterior hasta el lado frontal. La primera seccion incluye,en un área de la primera mitad del molde, la superficie optica encerrada por una circunferencia más externa del lente oftálmico.Se co-moldea una segundaseccion con la primera seccion, y bloquea la luz. La segunda seccion se dispone con respecto a la primera seccion, de tal manera que la segunda seccion impideque pase la luz de curado incidente en el lado posterior, a travésde la primera mitad del molde, hacia un área de la cavidad del moldeque se extiende desde ellado frontal de la primera mitad del molde hasta el lado frontal de la segunda mitad del molde, rodeando y extendiéndose radialmente hacia fuera de un límiteque incluye la circunferencia del lente oftálmico y de tal modo que la primera seccion pasa la luz incidente hacia un área de la cavidad del molde limitada por, y dentro de, el límite.
