Abstract
LENTE OFTALMICA QUE TIENE DOS SUPERFICIES REFRACTANTES. UNA DE LAS SUPERFICIES DE REFRACCION INCLUYE UNA PRIMERA CURVA MERIDIANA IMAGINARIA QUE SE PROLONGA EN LA DIRECCION VERTICAL A LO LARGO DE LA SUPERFICIE DE REFRACCION CUANDO SE VE DESDE UNA DIRECCION ORTOGONAL CON RESPECTO A ELLA. LA DISTRIBUCION DEL RADIO DE CURVATURA DE LA CURVA MERIDIANA INCLUYE UNA ZONA EN LA QUE AQUEL DISMINUYE GRADUALMENTE DESDE UNA PARTE SUPERIOR A UNA INFERIOR DE LA CURVA, SIENDO LOS RADIOS DE CURVATURA EN LAS INTERSECCIONES DE CURVAS ORTOGONALES QUE SE CRUZAN EN ANGULO RECTO CON LA CURVA MERIDIANA EN LA SUPERFICIE DE REFRACCION, IGUALES A LOS RADIOS DE CURVATURA DE LA CURVA MERIDIANA EN ESAS INTERSECCIONES, DE MANERA QUE EL ASTIGMATISMO A LO LARGO DE LA CURVA MERIDIANA EN LA SUPERFICIE DE REFRACCION ES CASI IGUAL A CERO, DIVIDIENDO LA CURVA MERIDIANA A LA SUPERFICIE DE REFRACCION EN DOS ZONAS LATERALES MAS PROXIMAS AL LADO NASAL Y AL LADO TEMPORAL.
