Unverified不要仅凭'低蓝光'宣传就选购而忽视频闪：部分低蓝光屏使用PWM调光，虽降蓝光但频闪伤眼，护眼效果被抵消，务必同时确认'无频闪/Flicker-Free'80% similarUnverified护眼级智能灯需同时满足显色指数Ra≥90、无可视频闪（波动深度＜8%）、无蓝光危害RG0认证，仅标注'低蓝光'而无认证的产品参考价值有限80% similarUnverified所谓'防蓝光认证等级'存在误区：优质护眼灯是通过降低有害短波蓝光峰值（415-455nm）实现RG0无危害级，而非加黄色滤光片降色温；靠偏黄滤光的'防蓝光'反而降低显色性和照度79% similarUnverified所谓'防蓝光认证'并非越强越好，过度过滤蓝光会导致偏黄失真和显色下降；正规护眼灯通过RG0无蓝光危害等级即可，无需单独追求防蓝光镀膜78% similarUnverified护眼关键看频闪而非蓝光，认准通过IEEE 1789无频闪或RG0豁免级（无蓝光危害）认证，频闪深度＜3.2%为无频闪，纯靠'防蓝光'宣传的产品往往只是加黄光而牺牲显色77% similar
