护眼效果好坏更多取决于照射面积和均匀度，而非单纯亮度，宽发光面+导光板设计的大板灯比传统集中光源的小台灯眩光更小

Unverified亮度越高越'护眼'是误区：照度过高（＞1000lx）反而增加眩光和疲劳，理想是环境光与台灯亮度形成合理对比，建议开启环境背景光而非仅用台灯86% similarUnverified照度均匀度（最低/平均照度比）越高越好，专业护眼灯用透镜阵列或导光板实现均匀分布；单颗大功率LED裸露光源亮度高但中心过亮边缘暗，长期看书导致瞳孔频繁调节疲劳85% similarUnverified遮光设计（下沉式光源+防眩光板）比单纯高流明更重要，能看到裸露光珠或直视灯头刺眼的灯，即便照度达标也会造成眩光疲劳85% similarUnverified高照度与照射均匀性的权衡：单纯追求高亮度可能导致中心过亮边缘暗形成明暗反差反而伤眼，大发光面/导光板设计的均匀照明比高亮点光源更护眼84% similarUnverified亮度与护眼存在权衡：高显色高护眼的LED光效偏低，同瓦数下比廉价灯珠暗，追求护眼需接受选更高功率(建议阅读灯≥6W/400lm)而非最省电型号84% similar
