该创造发明的护眼装置的功率设计为 0. 5-5W, 主要在 1W左右， 对比常用的 40W的环境灯， 节能达 97. 5%
从实际缓解视疲劳效果看， 主体感觉眼睛舒适和湿润，检测发现眨眼次数提 升 20%左右。 因为用电脑的盯屏现象， 会使得眨眼次数从日常的每分钟 21次左 右， 锐减到每分钟 3-5次， 眼睛非常干涩。 眨眼次数的增加， 能让干涩状况得到 缓解。

实验显示护眼色谱卡 6的应用可以激活视细胞，调动视功能，减缓用眼过程 中的眼疲劳， 增强眼睛的舒适度， 可预防近视。 当人在近距离使用眼睛时， 为了 看清目标， 需依靠眼睛的调节功能对晶状体进行调节。通过眼睫状肌收缩， 使晶 状体的凸度增加， 从而增加屈光度， 使近处物象清晰可见。调节近点距离可以反 映眼睛的调节功能。 当产生眼疲劳时， 其调节近点距离会比正常时加大。在不使 用带护眼色谱卡 6的护眼装置时，绝大多数人在长时间使用电脑后均出现明显的 眼疲劳， 其调节近点距离均有所变远， 且前后差制值较大， 经统计学处理， 具有 极显著性差异 （p〈0. 001 ) ； 使用带护眼色谱卡 6的护眼装置时， 少数人也出现 调节近点距离加大，但大多数人调节近点距离变化不太明显，其差值均数无显著 性差异 （p>0. 05 ) ， 表明从总体水平看未出现明显眼疲劳， 详见下表： 使用电脑前后调节近点距离变化
Figure imgf000011_0001
如图 14所示， 根据实验得到使用电脑护眼装置后， 待检测的人群的眨眼次 数的数据统计结果是：使用护眼装置时眨眼次数与未使用护眼装置时眨眼次数相 比较在对应的时间上明显增加， 眼干与视疲劳得到缓解。
如图 10所示， 当用于笔记本电脑时， 将弧形夹 24子插入导入槽， 夹持在电 脑屏幕上即可， 将角度调节到不看到光源即可。 通过铰链组件实现角度的调节， 并且第一凹凸槽组 171和子圆筒凸起 181配合实现角度的固定。 第一防滑垫 21 和第二防滑垫 27， 加上弧形夹子的夹持力， 能让本装置稳固的夹持在电脑显示 器上。 在弧形夹不适于应用的台式机的显示器上采用 T形架 9加持。 将 T形架 9 插入导入槽， 将 T形架 9上的双面胶张贴在电脑屏幕顶部， 为了稳固， 将加固条 10纵向粘贴， 把 T形架 9和电脑显示器粘连一起。
以上对本发明创造的实施例进行了详细说明，但所述内容仅为本发明创造的 较佳实施例， 不能被认为用于限定本发明的实施范围。凡依本发明创造范围所作 的均等变化与改进等， 均应仍归属于本专利涵盖范围之内。
