Abstract

SE DESCRIBEN METODOS PARA FABRICAR LENTES PLASTICAS DE CALIDAD OPTICA CON ADITIVOS FOTOCROMICOS. DE ACUERDO CON UNA PRIMERA REALIZACION DE LA INVENCION, UNA RESINA DE MOLDEO QUE CONTIENE ADITIVOS FOTOCROMICOS SE DISPONE ENTRE UN MOLDE Y UNA PREFORMA DE LENTE Y A CONTINUACION VULCANIZA. DE ACUERDO A UNA SEGUNDA REALIZACION DE LA INVENCION, UNA RESINA DE MOLDEO SUSTANCIALMENTE LIBRE DE ADITIVOS FOTOCROMICOS SE DISPONE ENTRE UN MOLDE Y UNA PREFORMA DE LENTE Y A CONTINUACION VULCANIZA. A CONTINUACION LA RESINA ES IMPREGNADA CON ADITIVOS FOTOCROMICOS. EN UNA TERCERA REALIZACION, UNA RESINA DE ESTRUCTURA EN CAPAS QUE CONTIENE UN ADITIVO FOTOCROMICO SE SUMINISTRA A LA SUPERFICIE DE UN MOLDE Y VULCANIZA A UN ESTADO DE GEL. A CONTINUACION SE DISPONE UNA RESINA DE MOLDEO QUE ESTA SUSTANCIALMENTE LIBRE DE ADITIVOS FOTOCROMICOS ENTRE EL MOLDE REVESTIDO Y UNA PREFORMA DE LENTE Y VULCANIZA. DE ACUERDO A UNA CUARTA REALIZACION, SE SUMINISTRA UNA RESINA DE MOLDEO QUE ESTA SUSTANCIALMENTE LIBRE DE ADITIVO FOTOCROMICO A LA SUPERFICIE DE UN MOLDE Y VULCANIZA A UN ESTADO DE GEL. A CONTINUACION, UNA RESINA DE MOLDEO QUE CONTIENE ADITIVOS FOTOCROMICOS SE DISPONE ENTRE EL MOLDE REVESTIDO Y UNA PREFORMA DE LENTE Y VULCANIZA.
