Abstract

LA INVENCION SE REFIERE A UNA LENTE OFTALMICA MULTIFOCAL, QUE TIENE UNA SUPERFICIE ESFERICA (S) QUE PRESENTA EN CUALQUIER PUNTO UNA ESFERA MEDIA Y UN CILINDRO, Y QUE COMPRENDE UNA ZONA DE VISION DE LEJOS, UNA ZONA DE VISION DE CERCA, UNA ZONA DE VISION INTERMEDIA, UNA MERIDIANA PRINCIPAL DE PROGRESION QUE ATRAVIESA ESTAS TRES ZONAS. SEGUN LA INVENCION LA LONGITUD PRINCIPAL DE PROGRESION ES INFERIOR A 16 MM, Y LA ZONA DE VISION DE LEJOS ENGLOBA UN SECTOR ANGULAR QUE TIENE POR ORIGEN EL CENTRO GEOMETRICO DE LA LENTE Y UN ANGULO EN EL CENTRO SUPERIOR A 150°. ADEMAS LA ESFERA VARIA DE MANERA MONOTONA EN FUNCION DEL ANGULO EN UN CIRCULO DE RADIO DE 20 MM CENTRADO EN EL CENTRO GEOMETRICO DE LA LENTE, POR AMBAS PARTES DE LA MERIDIANA, COMO LO MUESTRA LA FIGURA. LA INVENCION GARANTIZA UNA BUENA DISTRIBUCION DE LAS LINEAS DE ISOCILINDRO Y DE ISOESFERA EN LA LENTE, Y ASI UNA GRAN SUAVIDAD DE LA LENTE.
