Abstract

PURPOSE:To obtain liquid crystal sunglasses whose depth changes automatically in accordance with external light by allowing a solar battery to serve as both a power source and a photosensor, and providing an oscillating circuit and a liquid crystal driving circuit. CONSTITUTION:The titled sunglasses are constituted of a solar battery 1, a lens 2 with a liquid crystal cell and a fame 3, and the lens 2 with a liquid crystal cell is brought to light-shielding, when a voltage is applied. Also, an oscillating circuit and a liquid crystal driving circuit are provided, and they consists of a power source stabilizing capacitor 4, capacitors 5, 6, resistances 7-10, transistors 11, 12, etc. In such a way, when the periphery is bright, the oscillating circuit is oscillated by energy of the solar battery 1, and the liquid crystal driving circuit operates, turns on a liquid crystal and deepens the glasses. That is, the depth of the sunglasses is varied automatically by the external light.
