Zusammenfassung:To provide a polarization photochromic optical article that has both a polarization function and a photochromic function, has an effective antiglare property, and furthermore has a high adhesion.SOLUTION: A polarization photochromic optical article includes: a lens substrate having a polarization function; a primer layer; and a photochromic layer having a photochromic compound, in this sequence. In the polarization photochromic optical article, the polarization degree of the optical article is 30-100%, the luminous transmittance of the optical article when the photochromic layer colors is 5-40%, and the luminous transmittance of the optical article when the photochromic layer is not coloring is 10-80%.SELECTED DRAWING: Figure 1 【課題】偏光機能とフォトクロミック機能の両方を併せ持つ効果的な防眩性を有し、更に密着性も良好である偏光フォトクロミック光学物品を提供する。【解決手段】偏光機能を有するレンズ基材、プライマー層、およびフォトクロミック化合物を含むフォトクロミック層をこの順で有する偏光フォトクロミック光学物品であって、該光学物品の偏光度が30〜100%であり、該フォトクロミック層が発色した時の該光学物品の視感透過率が5〜40%であり、該フォトクロミック層が発色していない時の該光学物品の視感透過率が10〜80%である偏光フォトクロミック光学物品を提供する。【選択図】図1
