Abstract: The present invention relates to an optical article that includes, a mark that is positioned on and/or within the first surface of an optical substrate thereof, and a photochromic layer that includes at least one photochromic compound and which resides over at least a portion of the first surface. The mark includes a photoluminescent material. The first surface of the optical substrate is exposed to a source of actinic radiation, the photochromic compound has an activation time after exposure to the source of actinic radiation, and the mark luminesces and is visually observable during at least a portion of the activation time. The present invention also relates to: an optical article that includes, a mark that is positioned within the first surface of an optical substrate thereof, and at least one photochromic compound that is also positioned within the first surface; and methods of making such optical articles.

Abstract: The present invention relates to an optical article that includes, a mark that is positioned on and/or within the first surface of an optical substrate thereof, and a photochromic layer that includes at least one photochromic compound and which resides over at least a portion of the first surface. The mark includes a photoluminescent material. The first surface of the optical sub-strate is exposed to a source of actinic radiation, the photochromic compound has an activation time after exposure to the source of actinic radiation, and the mark luminesces and is visually observable during at least a portion of the activation time. The present invention also relates to: an optical article that includes, a mark that is positioned within the first surface of an optical substrate thereof, and at least one photochromic compound that is also positioned within the first surface; and methods of making such optical articles.
