MULTI-CURVATURE EDGE FOR OPHTHALMIC LENSES

Abstract:

An exemplary ophthalmic lens includes an optic comprising an anterior optic surface and a posterior optic, and a multi-curvature optical edge surrounding the optic and connecting the anterior optic surface to the posterior optic surface, the multi-curvature optical edge comprising a plurality of tangentially-connected curved surfaces configured to mitigate positive dysphotopsia by directing or diffusing from light incident on the multi-curvature optical edge away from a fovea of a patient.
