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

Unverified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96% similarUnverified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95% similarUnverified有害蓝光集中在415-455nm波段，选购应关注该波段阻断率≥30%，而非笼统宣称的'阻断蓝光90%'（后者通常包含无害的455-500nm）93% 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93% similarUnverified选购时优先看标注的『有害蓝光波段（415-455nm）阻隔率』而非『全蓝光阻隔率』：真正伤眼的是短波高能蓝光，只标全波段阻隔率的产品往往靠牺牲透光率虚增数据92% similar
