Patent ID: 7380937

Claim:
A series of contact lenses, each lens in the series having a targeted optical power within the range of −15 diopters to 10 diopters for correcting myopia or hypermetropia, each lens in the series comprising an anterior surface having a first central optical zone and an opposite posterior surface having a second central optical zone, wherein the second central optical zones of all the lens in the series are substantially identical to each other and are aspherical surfaces, wherein the first central optical zone of each lens in the series has an aspherical design that, in combination with the second central optical zone, provides an optical power profile selected from the group consisting of (1) a substantially constant optical power profile, (2) a power profile mimicking the optical power profile of a spherical lens with an identical targeted optical power, and (3) a power profile in which lens spherical aberration at 6 mm diameter is from about 0.65 diopter to about 1.8 diopters more negative than spherical aberration at 4 mm diameter.
