    • Electronic sunglasses of the transmittance-varying type including liquid crystal panels employing the electro-optical effect and a solar cell used as a power source. The electronic sunglasses include a voltage detecting circuit having such a hysteresis characteristic so as to output a signal for changing transmittance of the liquid crystal panel from a high mode to a low mode at at least high predetermined voltage or illumination, and changing transmittance from a low mode to a high mode at at least a low voltage or illumination. The sunglasses also include a first switch which operates at at least two switch positions, one switch position having a first stage of illumination at less than 20,000 Lux and a second stage of illumination at 20,000 Lux or greater at which transmittance is changed from a high mode and another switch position disabling the voltage detecting circuit. Also included is a second switch which operates to change transmittance from a high mode to a low mode independently of the set voltage value in the voltage detecting circuit according to the hysteresis effect.
    • 透射率变化型的电子太阳眼镜包括采用电光效应的液晶面板和用作电源的太阳能电池。 电子太阳眼镜包括具有这种滞后特性的电压检测电路,以便在至少高的预定电压或照度下输出用于将液晶面板的透射率从高模式改变为低模式的信号,并将透射率从低 模式至少在低电压或照明下达到高模式。 太阳镜还包括在至少两个开关位置操作的第一开关,一个开关位置具有小于20,000LUX的第一阶段的照明,以及在20,000LUX或更大的第二阶段的照明,其中透射率从高模式 以及禁止电压检测电路的另一开关位置。 还包括第二开关,其操作以根据滞后效应独立于电压检测电路中的设定电压值而将透射率从高模式改变为低模式。
