Abstract

METODO PARA LA FORMACION DE LENTES PARA GAFAS CON CALIDAD OPTICA DE PLASTICO SE PRESENTA UN METODO RAPIDO, BASTANTE BARATO Y SENCILLO PARA LA PRODUCCION DE LENTES PROGRESIVAS O MULTIFOCALES DE PLASTICO ACABADAS A PARTIR DE UNA LENTE PREFORMADA QUE TENGA UNA CORRECCION VISUAL PREDETERMINADA (ES DECIR, CURVATURA O PRESCRIPCION) EN SU CENTRO OPTICO. EL METODO CONSISTE EN PROPORCIONAR UN MOLDE; PROPORCIONAR UNA COMPOSICION DE RESINA DE CALIDAD OPTICA; PROPORCIONAR UNA LENTE DE PLASTICO PREFORMADA EN CONTACTO CON LA LENTE PREFORMADA CON EL MOLDE DE TAL MODO QUE LAS SUPERFICIES DE LA LENTE PREFORMADA Y EL MOLDE FORMEN UNA CAVIDAD QUE ENCIERRE AL COMPONENTE DE RESINA; Y CURAR LA COMPOSICION DE RESINA. A LA CAVIDAD FORMADA POR LA LENTE PREFORMADA Y EL MOLDE SE LE DA FORMA, ENTRE OTRAS COSAS, (1) PARA QUE SE CORRESPONDA CON EL CAMBIO DE CURVATURA DESEADO Y (2) PARA QUE LA CORRECCION DE LA LENTE EN EL CENTRO OPTICO DE LA LENTE RESULTANTE SEA SUSTANCIALMENTE IGUAL (PREFERENTEMENTE IGUAL) A LA CORRECCION DE LA LENTE PREDETERMINADA EN EL CENTRO OPTICO DE LA LENTE PREFORMADA. LA LENTE PREFORMADA SE PUEDE MOLDEAR TAMBIEN CON UNA CAPA DE NO PRESCRIPCION DELGADA QUE ACTUA COMO PORTADORA DE LA REGION PROGRESIVA O MULTIFOCAL DE LA LENTE ACABADA. SE PRESENTAN LOS METODOS QUE PERMITEN MOLDEAR LENTES SIN TENER QUE UTILIZAR LAS JUNTAS OPTICAS CONVENCIONALES QUE RESULTAN CARAS. ESTOS METODOS PERMITEN TAMBIEN LA REPOSICION DEL CENTRO OPTICO AL LUGAR ADECUADO RESPECTO A LA PRESCRIPCION PROGRESIVA O MULTIFOCAL, PREFERENTEMENTE SIN TENER QUE UTILIZAR LAS JUNTAS OPTICAS CONVENCIONALES O LOS DESPLAZADORES DEL CENTRO OPTICO.
