Abstract

SE DESCRIBE UN CRISTAL DE GAFAS PROGRESIVO, DONDE SE APORTA AL MENOS UNA SUPERFICIE PARA EL AUMENTO DEL EFECTO DE PIEZAS DISTANCIADAS SOBRE LA ZONA DE PROGRESION PARA LA PIEZA CERCANA Y DONDE LOS RADIOS DE LA CURVATURA DE LAS CURVAS DE CORTE (CORTES HORIZONTALES) DECRECEN LA SUPERFICIE O SUPERFICIES, QUE APORTAN PARA EL AUMENTO DEL EFECTO, CON PLANOS HORIZONTALES COMO FUNCION DE LA ELIMINACION DE MERIDIANOS PRINCIPALES EN LA SUPERFICIES DELANTERA EN EL CAMPO DEL MERIDIANO PRINCIPAL EN PIEZAS DISTANCIADAS Y CRECEN EN PIEZAS CERCANAS Y CRECEN EN LA SUPERFICIE LATERAL AL OJO EN LA PIEZA DE LA DISTANCIA Y DECRECEN EN LA PIEZA CERCANA, Y SE INVIERTEN EL TRANSCURSO DEL CAMBIO DE LA CURVATURA ( RH = RH (X, Y) - RH (O1X)) CON DISTANCIA CRECIENTE DEL MERIDIANO PRINCIPAL. EL CRISTAL DE LAS GAFAS CNFORME AL INVENTO SE CARACTERIZA A TRAVES DE LA COMBINACION DE LOS SIGUIENTES DISTINTIVOS: - EL TRANSCURSO DEL CAMBIO DE LA CURVATURA ( RH) DEL TRAMO HORIZONTAL CON DISTANCIA CRECIENTE DEL MERIDIANO PRINCIPAL ESTA INDICADA A TRAVES DE LA SUPERPOSICION DE DOS FUNDIONES F1 (X1Y) Y F2 (X1Y): RH = F(X1Y) = F1 (X (POR) Y) + F2 (X1Y); - CONFORME A LA PRIMERA FUNCION F1 (X (POR) Y) DECRECE EL RADIO DE LA CURVATURA EN LA SUPERFICIE DELANTERA EN PRIMER LUGAR EN LA, O SEA, PARA LA SUPERFICIE LATERAL DEL OJO, DONDE SE INVIERTE EL CAMBIO DEL RADIO DE LA CURVATURA EN UNA DISTANCIA DE 14 A 26 MM DE MERIDIANO PRINCIPAL; - CONFORME A LA SEGUNDA FUNCION F2 (X1Y) CRECE EL RADIO DE LA CURVATURA EN LA SUPERFICIE DELANTER EN PRIMER LUGAR DEL O EN LA SUPERFICIE LATERAL AL OJO, DONDE SE INVIERTE EL CAMBIO DEL RADIO DE LA CURVATURA EN UNA DISTANCIA DE 14 A 26 MM DE MERIDIANOS PRINCIPALES; - EL VALOR ABSOLUTO DE LAS AMPLITUDES DE AMBAS FUNCIONES SE CAMBIA LONGITUDINALMENTE DEL MERIDIANO PRINCIPAL AL MENOS EN LA ZONA DE PROGRESION EN CONTRASENTIDO; - AL MENOS EN EL CAMPO DE LA PIEZA DISTANCIADA VALE COMO PARA UNA BANDA DERECHA E IZQUIERDA DE MERIDIANOS PRINCIPALES: (DELTA) F2 (DELTA) X (X = XO1 Y = YO) > (DELTA)F1 (DELTA) X (X = XO1 Y = YO), DONDE (DELTA) F1 (DELTA) X ES LA PRIMERA DERIVACION DE LA FUNCION F DESPUES DE X.
