1. A photochromic article comprising an at least partially cured polymerizable photochromic polymer composition comprising (1) a reaction product of:

  • (a) at least one photochromic material having at least one group polymerizable via addition polymerization; and

    (b) at least one material copolymerizable with said photochromic material (a); and

    (2) a material co-polymerizable with said polymerizable photochromic polymer composition, such that the reaction product comprising the photochromic article provides a Fade Half Life in the Photochromic Polymer Performance Test reduced over that provided by a photochromic material free of polymerizable groups.
