Unverified护眼灯必须通过IEEE 1789-2015豁免级（无风险）频闪标准，即在3.125Hz以下调光深度极低；标注'无可视频闪'但无第三方检测报告的产品不可信，PWM调光频率应≥3000Hz或采用DC恒流调光85% similarUnverified护眼看类DC调光或高频PWM调光（≥1920Hz），单纯的'低蓝光认证'（如莱茵TÜV）不解决频闪问题；对频闪敏感人群优先查PWM调光频率而非蓝光认证标签85% similarUnverified追求健康护眼应选支持PWM频率≥3125Hz或DC恒流调光的灯带，并有无频闪/低蓝光认证（如莱茵TÜV Low Blue Light、IEEE 1789无频闪）；低价灯带常用低频PWM调光，调暗时频闪加剧84% similarUnverified有RG0认证但仍需注意频闪：选购确认标注'无可视频闪'或频闪深度<波动深度国标限值，PWM调光低频段（<1250Hz）在低亮度下频闪明显，直流调光（DC调光）更护眼83% similarUnverified真正无频闪需认准DC调光而非高频PWM调光，PWM调光频率≥3840Hz才能基本消除频闪对眼睛的影响，低于此值长时间使用易疲劳83% similar
