Abstract

Se describen las lentes de contacto (201) y métodos de fabricación de las mismas. La lente (201) incluye una zona óptica (202). La zona óptica (202) comprende una región central (205), la región central (205) que tiene un primer eje óptico (219), una potencia de curvatura radial base, una potencia sagital radial base y un centro de curvatura que se encuentra en el primer eje óptico (219). La zona óptica (202) comprende una región anular (203), en la que en un punto a mitad de camino a través de la anchura de la región anular (203) la región anular (203) tiene una potencia de curvatura radial de X, en la que X es mayor que la potencia de curvatura radial base. La región anular (203) tiene un centro de curvatura fuera del eje que es una primera distancia del eje óptico (219) tal que, en un punto a mitad de su anchura, la región anular (203) tiene una potencia sagital de Y, en la que, Y es mayor que la potencia sagital radial base, y en la que Y es menor que X.
