The present invention provides a plastic article containing suspended photochromic dye molecules, and the said suspended photochromic dye molecules suspended in liquid micro-droplets of a suspension medium, and the said micro-droplets of the said suspension medium containing the said suspended photochromic dye molecules are embedded inside a solid polymer matrix, and the said solid polymer matrix is formed by polymerization of liquid polymer precursors. The invented structure of a plastic article containing suspended photochromic dye molecules exhibits fast response time and enhances photochromic performance.
