Abstract

UNA LENTE DE CONTACTO QUE TIENE UNA ZONA OPTICA CENTRALMENTE LOCALIZADA. LA ZONA OPTICA ESTA SUBDIVIDIDA DENTRO DE AL MENOS UN AREA DE DISTANCIA QUE TIENE AL MENOS UN PUNTO FOCAL Y AL MENOS UN AREA DE LECTURA QUE TIENE AL MENOS UN PUNTO FOCAL. EL AREA DE DISTANCIA SE LOCALIZA EXCLUSIVAMENTE EN LA PARTE MAS ALTA Y EL AREA DE LECTURA SE LOCALIZA EXCLUSIVAMENTE EL LA PARTE MAS BAJA DE LA ZONA OPTICA. EL BORDE SUPERIOR DE LA LENTE DE CONTACTO TIENE UNA CURVATURA MAYOR QUE LA DE LOS DOS BORDES DEL MISMO, DE MODO QUE LA FORMA DE LA LENTE ES OVALADA TENIENDO UNA DIMENSION VERTICAL MAS LARGA QUE LA HORIZONTAL. PREFERIBLEMENTE, EL BORDE INFERIOR DE LA LENTE DE CONTACTO TIENE UNA CURVATURA MENOS PRONUNCIADA QUE LA DEL BORDE SUPERIOR DEL MISMO Y PUEDE INCLUSO TENER UNA CURVATURA MENOS PRONUNCIADA QUE LA DE LOS BORDES LATERALES, ESPECIFICAMENTE DE MODO QUE LA CURVATURA DEL BORDE INFERIOR DE LA LENTE DE CONTACTO ESENCIALMENTE CORRESPONDE A LA CURVATURA DEL PARPADO INFERIOR DEL USUARIO. PARA PROPOSITOS DE POSICIONAMIENTO MAS PRECISO DE LA LENTE DE CONTACTO, EL GROSOR DE LA LENTE INCREMENTA GRADUALMENTE DESDE LA PARTE SUPERIOR A LA INFERIOR.
