Abstract

CRISTAL PARA GAFAS. COMPRENDE UNA SUPERFICIE ANTERIOR CONVEXA DE ROTACION SIMETRICA QUE MUESTRA UNA PARTE DE ACCION ASFERICA, SEGUIDA DE UNA ZONA DE TRANSICION ASI COMO UNA ZONA MARGINAL, Y CON UNA SUPERFICIE CONCAVA POR EL LADO DE LOS OJOS QUE CON LA ZONA MARGINAL FORMA UN BORDE DE SOPORTE. LA DISTANCIA DE UN PUNTO EN LA PARTE ACTIVA HASTA EL VERTICE DE LA SUPERFICIE ANTERIOR O FRONTAL EN DIRECCION DEL EJE OPTICO VIENE DADA POR LA ECUACION (I) SIENDO H LA DISTANCIA DE ESTE PUNTO HASTA EL EJE OPTICO Y C QUEDA DETERMINADO POR EL VALOR DE REFRACCION DE LA SUPERFICIE FRONTAL EN EL VERTICE, ESTANDO DETERMINADOS LOS COEFICIENTES ASFERICOS K, I , I , I E I DE MANERA QUE _!~HR + ~HS EN TODO EL CAMPO DEL ANGULO VISUAL SEA MINIMO, SIENDO ~HR EL ERROR DEL VALOR DE REFRACCION Y ~HS EL ASTIGMATISMO.
