  • Toric contact lenses
    Patent number: 8684521
    Abstract: A set of toric contact lenses, where each lens in the set includes a posterior surface and an anterior surface. For each lens in the set, at least one of the posterior and anterior surfaces includes a toric optical zone. Each lens in the set has a common effective base curve and a common overall diameter, but a different cylindrical correction. Lenses in the set have a peripheral zone and a blend zone disposed between the peripheral zone and the toric optical zone. In lenses of such a set, the width of said blend zone at a common location on at least two of the lenses are selected to be different so that the thicknesses at a common position on the lenses are substantially the same for all lenses in the set.
