PHOTOCHROMIC OPTICAL ARTICLES PREPARED WITH REVERSIBLE THERMOCHROMIC MATERIALS

摘要

Provided is a photochromic optical articleincluding: (a) an optical substrate; (b) a thermally reversible photochromic material; and (c) reversible thermochromic material capable of at least partially filtering UV/visible light at or below room temperature and becoming less capable of filtering UV/visible light at temperatures greater than room temperature.
