如公告号CN202102189U，公开日为2012.01.04的中国专利：一种防司机瞌睡报警眼镜，其公开了利用红外线来检测人眼的闭合时间，通过是否接收到反射的红外线时间间距来判定是否处于瞌睡状态或正常眨眼状态，进而进行防瞌睡报警。但是红外检测存在一定的局限性，人眼的闭合状态不易检测，如可能因为意外情况眯眼，可能会导致检测的失误。
如公告号CN202975517U，公开日为2013-06-05的中国专利：防瞌睡眼镜，其公开了动态感应器内部设有一个能够上下摆动的弧形的导体片，导体片的前部分成上下两片，导体片中放有金属重力球，利用瞌睡时的头部的摆动，来实现金属重力球的移动，从而使得导体片导通，来实现防瞌睡的检测，但是该种方式，其只能检测单一方向的，其检测方向由安装的导体片的安装位置决定，其不能实现多个角度的检测。同理采用水银开关，也会存在相似的问题，只能根据水银开关的安装方向来进而限定检测角度，同时液体会有吸附力，导致不灵敏，同时水银开关的液滴是装设在玻璃管内，而玻璃管存在易破损的风险。
