Unverified80% confidenceDecision RuleTime unknown
护眼看PWM调光频率而非厂商宣传的护眼认证，认准1920Hz或3840Hz+高频PWM调光；低于1440Hz的调光在低亮度下对敏感人群易致眼疲劳，SGS/莱茵认证只是加分项

Unverified追求护眼选高频PWM调光屏：1920Hz或2160Hz高频PWM明显优于1440Hz以下，对光敏感人群应认准≥1920Hz + 类DC调光 + 无频闪/低蓝光双认证91% similarUnverified真正护眼需高频PWM调光（≥1920Hz）或原生DC调光，1920Hz以下的PWM调光在低亮度时频闪明显，敏感人群仍会眼疲劳90% 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89% 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89% similarUnverifiedPWM调光频率≥1920Hz或采用类DC调光才算真正护眼，低于360Hz的低频PWM长时间使用易导致眼疲劳；对频闪敏感人群应认准全程DC调光或高频PWM≥2160Hz机型88% similar
