A system for customization of a photochromic article (14) includes a container (12) having an interior (28). At least one actinic radiation source (34) is located in the interior (28) of the container (12). At least one deactivation radiation source (36) is located in the interior (28) of the container (12). A method of customizing a photochromic article (14) includes inserting a photochromic article (14) having at least one non-thermally reversible photochromic material into a container (12) having at least one actinic radiation source (34) and actuating the at least one actinic radiation source (34) to activate the at least one non-thermally reversible photochromic material.
