Its basic principle is to monitor the arc light automatically by the photosensors; the photoelectric signal is analysed and processed automatically by the microprocessor, then it drives the liquid crystal light valve to turn from a "clear state" into a "dark" protective state rapidly . Meanwhile , when the arc light disappears, the system makes the liquid crystal light valve resumed the bright attitude by auto-delay,and microprocessor adjusts eye protection circuit intelligently to reduce the consumption in the maximal degree, which make the working time achieved one or two years by ordinary button cell cooperates with photocells .

其基本原理是由光敏器件自动监测弧光，光电信号经微处理器自动分析处理，快速驱动液晶光阀由透明的亮态迅速变为保护的暗态，当弧光消失时自动延时使液晶光阀恢复亮态；并且微处理器智能调整护目镜电路的工作姿态，最大程度降低功耗，使得普通的扣式电池配合光电池便可以工作一至两年。
