    Abstract: A method of coating an edge surface of an optical lens is provided. The method includes providing an optical lens comprising a first optical surface and an opposing second optical surface, wherein the first and the second optical surfaces are connected by an edge surface, disposing at least one temporary protective material on at least a portion of a perimeter portion of one or both of the first and the second optical surfaces abutting the edge surface, disposing at least one coating material on the edge surface of the optical lens to obtain at least one edge coating, and removing any excess coating material disposed on the at least one temporary protective material. An optical lens having at least one temporary protective material disposed on only at least a portion of a perimeter portion of one or both of the first and the second optical surfaces abutting the edge surface is also provided.
