Abstract

SE DESCRIBE UN CRISTAL PARA GAFAS PROGRESIVO CON UNA PIEZA A DISTANCIA, CUYO VALOR DE REFACCION SE DIMENSIONA PARA LA VISTA PARA LEJOS, CON UNA PIEZA A CORTA DISTANCIA (CERCA) Y CON UNA PIEZA INTERMEDIA, DONDE EL VALOR DE REFRACCION SE AUMENTA A LO LARGO DE LA LINEA VISUAL PRINCIPAL DEL VALOR DE REFRACCION DE LA PIEZA A DISTANCIA AL MENOS PARCIALMENTE, CONTINUAMENTE SOBRE EL VALOR DE REFRACCION DE LA PIEZA A CORTA DISTANCIA. EL CRISTAL PARA GAFAS CONFORM EL INVENTO SE CARACTERIZA DE TAL MANERA, QUE UN INDICE DE REFRACCION DEL MATERIAL DEL CRISTAL VARIABLE AL MENOS EN LA PIEZA INTERMEDIA, A LO LARGO DE LA LINEA VISUAL PRINCIPAL, SE CONTRIBUYE AL MENOS PARCIALMENTE PARA EL AUMENTO DEL VALOR DE REFRACCION.
