光致变色镜片是眼镜产品中高价值的产品，有广阔的应用前景。本文从光致变色镜片的原理出发，总结归结出变色质量的三大指标：变色程度、变色速度和变色寿命，同时结合实际的检测工作，探讨了标准存在的问题和检测工作中需要注意的问题，最后提出了光致变色镜片的发展方向。“,”Photochromic lens are high-value optical products with broad application prospects. In the light of principles concerning photochromic lens, the present study summarizes three indicators denoting quality of lens, namely, al ochromasia degree, al ochromasia velocity and al ochromasia longevity. In the meantime, the study approaches some problems arising during enforcing standards or inspecting products that require attentions, combining with practical inspection work. Final y there comes up the developing direction for photochromic lens.
