Abstract: An ophthalmic lens may comprise a posterior optic surface, an anterior optic surface, and an optic edge between the posterior optic surface and the anterior optic surface, wherein the optic edge forms a substantially circular perimeter having a thickness that varies periodically. The thickness of the optic edge may vary periodically for at least two cycles. Additionally, or alternatively, the ophthalmic lens may comprise an optic skirt coupled to the optic edge. The optic skirt can be configured to inhibit transmission of light around the optic edge.
