摘要:
A photochromic lens is proposed which can lose its color in a shorter period of time, and which is less likely to deteriorate when exposed to ultraviolet radiation. The photochromic lens is formed by dissolving 0.03 to 0.2 parts by mass of a spirooxazine photochromic compound in tetrahydrofuran, mixing the solution thus obtained into 100 parts by mass of a lens resin material so that the photochromic compound is uniformly dispersed in the resin material.
