摘要：
A liquid crystal spectacle includes a pair of liquid crystal lenses and a frame holding the lenses. The frame has a pair of temples and a pair of ear pieces attached individually to the temples. Each ear piece houses a battery for supplying the voltage to the corresponding lens. Each temple houses a regulator circuit for regulating the voltage supplied from the battery to the lens, thereby controlling the refractive index of the lens.
