Abstract

La presente invencion se refiere a una lente oftálmica progresiva, caracterizada porque tiene: una porcion de distancia, una porcion de lectura y una porcion intermedia; la lente que tiene una superficie de energía progresiva compuesta zC definida por la ecuacion: ZC(A)=ZH(A-B)+ZS(B)-ZH(O) en donde: ZC = elevacion de la superficie de energía progresiva sobre un plano de referencia; ZH = elevacion de la superficie de energía progresiva sobre el plano de referencia para un primer componente de diseño de la lente; ZS = elevacion de la superficie de energía progresiva sobre el plano de referencia para el segundo componente de diseño de la lente; ZO = elevacion de la curva base sobre el plano de referencia para uno de los componentes del diseño; A = adicion de energía de la lente compuesta; y B = adicion de energía del segundo componente de diseño.
