摘要：
An optical lens has a first curved surface. The first curved surface has a first variable curvature. The optical lens has a second curved surface. The second curved surface has a second variable curvature. The second variable curvature forms a protrusion on the second curved surface. A first end of the first curved surface is connected to a first end of the second curved surface at an outer edge of the lens.
