Abstract

SE DESCRIBE UN CRISTAL DE LENTES CON EFECTO PROGRESIVO, QUE MUESTRA AL MENOS UNA SUPERFICIE EN DONDE EL PODER FOCAL CAMBIA DE TAL MODO, QUE AL MENOS UNA REGION EN DONDE EL EFECTO DE LAS LENTES ES APROXIMADAMENTE CONSTANTE, CAMBIA EL MENCIONADO EFECTO A LO LARGO AL MENOS DE UNA LINEA (REFERIDA EN ADELANTE COMO LA LINEA PRINCIPAL) QUE PUEDE ESTAR EN UN PLANO O CURVADA Y SOBRE LA CUAL SE DISPONE DE UN ASTIGMATISMO PREDETERMINABLE NO IGUAL AL CERO PDT. LA INVENCION SE DISTINGUE PORQUE EL ASTIGMATISMO DE SUPERFICIE SOBRE LA LINEA PRINCIPAL NO TIENE SOLAMENTE UN VALOR DADO SINO TAMBIEN UNA POSICION AXIAL GENERALMENTE NO CONSTANTE A LO LARGO DE LA LINEA PRINCIPAL, DE TAL MODO QUE EL ASTIGMATISMO TOTAL DEL RAYO RESULTANTE, TENIENDO EN CUENTA EL RAYO OBLICUO ASTIGMATICO, ES VIRTUALMENTE CONSTANTE HACIA LA SUPERFICIE DEL LADO DEL OJO A LO LARGO DE LA LINEA PRINCIPAL O ES VARIABLE EN AMBOS VALORES Y POSICION AXIAL DE ACUERDO CON REQUERIMIENTOS FISIOLOGICOS.
