Optical device with desensitized rotational angular alignment for astigmatism correction

Abstract:

An ophthalmic lens comprises a main body having a toric surface and a spherical surface opposite the toric surface, the main body comprising an eyelid stabilization design structure having a thickness of less than 200 .mu.m, wherein the spherical surface is configured to exhibit a lens spherical power, wherein the toric surface is configured to exhibit a lens cylindrical power that does not fully correct ocular cylindrical power due to astigmatism; and wherein the lens spherical power is configured such that the minimum circle of the ophthalmic lens is on or adjacent the retina of the eye of the wearer at a target angle of alignment.
