真正护眼要看'硬件低蓝光'和'DC调光/不闪屏'，而非软件降蓝光；PWM低频调光（<1250Hz）在低亮度下频闪严重，敏感人群长时间使用易疲劳干涩

Unverified真正护眼需同时具备硬件级DC调光无频闪与TÜV莱茵低蓝光双认证，仅有软件降蓝光（偏黄模式）而无硬件无频闪的机型，在低亮度下仍会PWM频闪加重疲劳90% similarUnverified屏幕护眼看DC调光而非PWM调光，同时选择通过硬件低蓝光认证（如莱茵TÜV硬件级）的机型；软件低蓝光只是调色温，长时间用眼疲劳差异明显89% similarUnverified护眼不能只看防蓝光，真正减负担的是DC调光（无频闪）；低亮度下用PWM调光的屏幕即使有防蓝光认证仍会引起眼疲劳，认准硬件级不闪屏88% similarUnverified对频闪敏感（易头晕眼胀）人群应选择DC调光或高频PWM调光（≥1920Hz）机型，避免低频PWM（480Hz以下）OLED屏，可查看是否有莱茵低蓝光+无频闪双认证87% similarUnverified屏幕看PWM调光频率而非峰值亮度：对屏幕敏感/易眼疲劳者选高频PWM（≥1920Hz）或类DC调光机型，OLED低频闪烁是暗光下眼干头晕的主因87% similar
