Optical Device With Desensitized Rotational Angle Alignment for Astigmatism Correction

摘要

The ophthalmic lens comprises a body having a toric surface and a spherical surface opposite the toric surface, the body comprising a blephar stabilizing design structure having a thickness of less than 200 μm, wherein the spherical surface is configured to exhibit a spherical refractive power of the lens wherein the toric surface is configured to exhibit a lens circumferential power that does not fully correct the ocular circumferential power due to astigmatism, wherein the lens spherical power is such that the minimum circle of the ophthalmic lens is at a target alignment angle on the retina of the wearer's eye or It is configured to be adjacent thereto.
