摘要:
A toric ophthalmic lens having substantially zero spherical aberration for a first circular aperture having a first diameter and substantially zero spherical aberration for a second circular aperture having a second diameter, the first diameter being at least 4 mm and the second diameter being at least 3 mm, the first diameter being at least 0.5 mm larger than the second diameter. A series of ophthalmic lenses, each lens comprising a same spherical power as the other lenses in the set, and a unique cylindrical power, each lens comprising (i) a first toric surface, and (ii) a second surface, at least one of the first surface and the second surface being aspheric in a meridian, the lens having substantially zero spherical aberration for all circular optical zone diameters less than 4 mm.
