Abstract:
    The invention is directed to a photochromic material that filters, from solar radiation, near infrared radiation and sufficient portions of ultraviolet radiation while transmitting actinic radiation in the wavelength range of about 341 - 5 nm. The light-transmitting photochromic material provides light and heat stability to achieve a longer useful life. This photochromic material is preferably incorporated in a multilayered structure with constituents provided on or contained within one or more layers to enhance the resistance to light fatigue.
