Abstract

La primera lente de contacto (1) se coloca sobre el ojo dominante e incluye un área esférico central (5) para la vision a distancia, la cual está rodeada por una área no esférica (78) que tiene una dioptría en la forma de adicion progresiva, la cual varía de la adicion cero a la periferia inferior a una adicion máxima en la periferia exterior y la cual permite la adicion, a todas las distancias incluyendo la lectura. La segunda lente de contacto (3) se coloca sobre el ojo dominado. El área central (13) es esférica y ajustada para la lectura. El área anular no esférica (15) tiene una reduccion progresiva de adicion máxima a adicion cero, lo cual permite la vision de la lectura a vision intermedia y a distancia, este sistema proporciona en la mayoría de los casos 95-100% de vision a todas las distancias.
