Zusammenfassung:	To provide a photochromic optical article having high performance.SOLUTION: A photochromic optical article includes a base material 1 containing a photochromic compound. The base material 1 includes a first main surface MS1 and a second main surface MS2 positioned opposite to the first main surface MS1, and also has a dye region RE1 having dye near the first main surface MS1. The amount of the dye in the dye region RE1 is more than that of dye near the second main surface MS2.SELECTED DRAWING: Figure 1 【課題】高性能なフォトクロミック光学物品を提供する。【解決手段】一実施形態によると、フォトクロミック光学物品が提供される。このフォトクロミック光学物品は、基材１を含む。基材１は、フォトクロミック化合物を含む。基材１は、第１主面ＭＳ１と、第１主面ＭＳ１と反対側に位置する第２主面ＭＳ２とを有しする。基材１は、第１主面ＭＳ１近傍に染料を含む染料領域ＲＥ１を有し、染料領域ＲＥ１における染料の量は、第２主面ＭＳ２近傍における染料の量よりも多い。【選択図】図１
