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.
本发明涉及一种光学产品,该光学产品包括:设置在光学基板第一表面上和/或其第一表面内的标记;以及光致变色层,该光致变色层包括至少一种光致变色化合物,并至少覆盖第一表面的一部分。标记包括光致
发光材料。光学基板的第一表面暴露于光辐射源,光致变色化合物在暴露于光辐射源后有一个活化时间,标记在至少一部分活化时间内发光并可目视观察。本发明还涉及:一种光学制品,包括设置在其光学基板第一表面内的标记,以及也设置在第一表面内的至少一种光致变色化合物;以及制造这种光学制品的方法。
