摘要： The present invention relates to photochromic articles that include a substrate and at least one photochromic material that is adapted to change from an unactivated form to an activated form by exposure to radiation substantially in the wavelength range from 380 to 450 nanometers when measured over a range of from 380 to 700 nanometers. The photochromic article is also adapted to retain at least 12 percent of the delta OD measured in the Outdoor Test when tested in the Behind the Windshield Test. The photochromic material can be selected from certain compounds including, for example, fluoranthenoxazines, naphthopyrans, phenanthropyrans, fluoranthenopyrans, and indenonaphthopyrans, which each have bonded thereto at least one chiral or achiral lengthening group that provides the photochromic compound with dichroic properties. The present invention also relates to methods of forming a photochromic article.
