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

Unverified防蓝光镜片分为基材内置型和镀膜反射型：基材染色型阻隔率高（可达30%以上）但镜片明显发黄，镀膜型阻隔率通常10-20%但色偏小，日常办公优先选镀膜型控制色偏96% similarUnverified基材阻隔型镜片（蓝光吸收剂融入镀膜基材）阻隔率通常30%-60%，镜片偏黄；镀膜反射型阻隔率约10%-20%但色偏小。长时间用眼且能接受偏色选基材型，办公需辨色选反射镀膜型92% 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91% similarUnverified防蓝光膜阻隔率与色偏成正比：阻隔率≥50%的膜通常泛黄严重，阻隔率30%-45%是护眼与色彩还原的平衡区间，摄影/设计用途应选≤30%90% similarUnverified防蓝光眼镜分为基材吸收型和镀膜反射型两类，基材吸收型（黄色调）对415-455nm短波蓝光过滤率可达30-60%但色偏明显，镀膜反射型阻隔率通常10-25%但接近无色，日常办公选镀膜反射型，重度屏幕暴露选基材吸收型90% similar
