摘要：
Provided is a photochromic optical article including: (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. The reversible thermochromic material (c) is operable for filtering light in the range of from 300 to 450 nanometers.
