Title: Optical lens and light source module having the same

Abstract: A lens for covering a light source to diverge light from the light source includes a first curved surface facing the light source, a second curved surface covering the first curved surface, and a connecting surface interconnecting bottoms of the first curved surface and the second curved surface. A plurality of first protrusions and second protrusions are formed on the connecting surface. The first protrusions and the second protrusions each are semi-terete.
