'防蓝光'与'高显色'存在权衡：削减蓝光会降低色温和显色指数，过度防蓝光的灯偏黄且Ra下降，追求Ra90+的护眼灯本质是用无频闪+合理照度+RG0达标而非单纯滤蓝光

Unverified'防蓝光'与'显色/色温'存在权衡：过度削减蓝光会使色温偏黄、Ra下降，真正护眼靠无频闪+合理照度，无需迷信强防蓝光镀膜95% similarUnverified所谓'防蓝光认证'台灯有陷阱：过度削减蓝光会导致色温偏黄、显色下降，真正护眼的核心是控制频闪+足够照度+Ra90，而非追求防蓝光等级92% similarUnverified过度追求'防蓝光'反而有害：合格护眼灯通过降低蓝光峰值达到RG0无危害即可，防蓝光镜片/黄光滤镜会导致色温偏黄、显色下降，与Ra≥90矛盾92% similarUnverified所谓'防蓝光'台灯若通过降低色温或加黄膜实现，会降低显色性并偏色，护眼应选无害蓝光认证（RG0豁免级）而非物理滤蓝光91% similarUnverified所谓'防蓝光'照明多为削减部分蓝光波段，会导致显色偏差和偏黄，护眼更应关注整体亮度充足、无频闪和合理色温而非单纯抑制蓝光。90% similar
