Abstract

La presente invencion describe un lente oftálmico progresivo que incluye una superficie del lente que tiene una zona de vision inferior que proporciona una buena calidad optica a una alta potencia superficial previamente determinada sobre una gran área de vision; dicha potencia se determina previamente por la prescripcion (Rx) de la persona que ve, la posicion de ajuste horizontal normalmente se determina por la distancia pupilar de cerca del usuario, y la posicion de ajuste vertical normalmente se determina por el punto intermedio del armazon vertical, la zona de vision superior de la potencia superficial inferior proporciona un incremento en la amplitud de la vision para las distancias de vision intermedia o mayores; y un corredor de una astigmatismo relativamente bajo que se extiende entre las mismas, en donde los contornos de la potencia superficial media y/o el astigmatismo superficial dentro de la zona de vision inferior, la zona de vidrio superior y el corredor son simétricos generalmente al meridiano vertical del lente como se ajusta al usuario.
