防蓝光眼镜按技术分两类：基材吸收型（镜片自带黄色底色）阻隔波长415-455nm有害蓝光更彻底，可达40-60%阻隔率；镀膜反射型（镜片近乎透明）阻隔率通常仅10-20%但色偏小，长期屏幕工作选基材吸收型，视频出镜/设计工作选镀膜型

Unverified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95% similar Unverified防蓝光镜片按阻隔波段分两类：反射膜片主要阻隔415-455nm短波蓝光(阻隔率通常20-40%)但镜片近无色偏；基材染色片可阻隔更宽波段(阻隔率可达60%以上)但镜片明显泛黄。日常办公选反射膜片，重度屏幕/护眼选染色片93% similar Unverified防蓝光镜片分为基材阻隔和镀膜反射两种：镀膜反射型镜片对415-455nm高能短波蓝光阻隔率可达30%以上但镜面泛蓝紫反光，基材吸收型蓝光阻隔更均匀（约15-25%）且色偏小，长时间办公优选基材吸收型92% similar 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90% similar Unverified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90% similar
