The present invention relates to optical articles that exhibit a uniform first transmittance when directly exposed to actinic radiation, such as sunlight; a gradient second percent transmittance when exposed to actinic radiation that has passed through an actinic radiation blocking or attenuating transparency (such as a vehicle windshield) interposed between the source of actinic radiation and the optical article; and a uniform third percent transmittance when free of exposure to actinic radiation. With the inventive optical articles, the uniform first percent transmittance is less than the uniform third percent transmittance. The present invention also relates to photochromic optical articles.
