Unverified防蓝光镜片分为基材吸收型和镀膜反射型：基材型（黄色底色）对415-455nm有害蓝光过滤率可达40-60%，镀膜型（表面泛蓝紫反光）过滤率通常仅10-30%但色偏小89% similarUnverified选择基材阻隔型（内添加防蓝光因子）而非镀膜反射型镜片，基材型对415-455nm有害蓝光的阻隔率通常20%-40%且镜片透明度高，镀膜型虽阻隔率可达60%但镜片明显反蓝紫光、易花且色偏严重89% similarUnverified蓝光阻隔分基材型和镀膜型两种：基材型（镜片本身偏黄）阻隔率可达50%以上但色偏明显；镀膜型阻隔率通常10-30%但几乎无色偏，日常办公防蓝光选镀膜型阻隔率15-25%即可兼顾护眼与色彩真实88% similarUnverified主流镀膜式防蓝光镜片对415-455nm蓝光过滤率约20-35%，基材染色式可达40-60%但镜片底色偏黄88% similarUnverified真正阻挡有害短波蓝光（415-455nm）的膜片通常呈现淡黄色，透明无色的蓝光膜阻隔率一般不超过15%，效果有限。宣称'完全无色透明还能挡蓝光60%'的产品需警惕88% similar
