真正有害的是415-455nm短波蓝光，选购时应看膜是否标注针对该波段的阻隔率，而非笼统的'蓝光阻隔'。仅标注400-500nm宽波段阻隔往往连有益的460-480nm蓝光也过滤，导致偏黄严重

Unverified真正有害的是415-455nm短波蓝光，选购时应关注该波段的阻隔率而非泛泛的"总蓝光阻隔率"，泛数字可通过阻隔无害的460-500nm蓝光虚高95% similarUnverified真正有害的高能短波蓝光集中在415-455nm波段，选购应关注对该波段的阻隔率而非笼统的蓝光过滤率。宣称'过滤90%蓝光'往往包含无害的455-500nm，需警惕数值虚标94% similarUnverified波长415-455nm的高能短波蓝光才是有害段，选购时应看该波段的过滤率（≥50%即达标护眼级），而非笼统的'蓝光过滤率90%'——后者常把无害的460-500nm段也算进去凑数94% similarUnverified选防蓝光膜要看阻隔的具体波段：真正伤眼的是400-455nm高能短波蓝光，合格膜应标注该波段阻隔率；只标'蓝光阻隔XX%'不注明波段的多为噱头93% similarUnverified真正有效的防蓝光膜应主要阻隔415-455nm高能短波蓝光，而非全波段；选购时看是否标注具体阻隔波段，只写'蓝光阻隔XX%'不标波段的多为噱头92% similar
