Unverified防蓝光膜主要阻隔400-450nm短波蓝光，实际阻隔率多在10%-40%之间；并非完全消除蓝光，不能替代科学用眼习惯92% similarUnverified蓝光阻隔率在415-455nm波段做到30%-40%即可有效防护有害短波蓝光，全波段阻隔率≥60%的镜片会导致明显黄色偏色且影响正常用眼91% similarUnverified防蓝光主要防护的是400-455nm高能短波蓝光，这段光对视网膜潜在损伤和数码眼疲劳关联最大，选购时应关注该波段的过滤率而非整体蓝光91% similarUnverified防蓝光膜阻隔波长应集中在415-455nm的高能短波蓝光段，此段对视网膜危害最大；标称阻隔30%-45%的膜透光率仍可维持85%以上，兼顾护眼与显示效果91% similarUnverified防蓝光膜的过滤率关键看415-455nm短波蓝光的阻隔比例，标称能阻隔40%以上短波蓝光的膜才有实质护眼意义，而宣称'过滤蓝光95%'的产品通常连有益蓝光都挡掉，会导致屏幕严重偏黄90% similar
