摘要
A contact lens, comprising a first surface and a tone second surface. The tone surface has a first meridian and a second meridian, and the toric surface has a first aspheric component in the first meridian. At least one of the first surface and the second meridian of the second surface has a second aspheric component, such that spherical aberration in the first meridian is within 0.1 microns (um) of being equal to the spherical aberration in the second meridian.
