Liquid crystal spectacles
First Claim
Patent Images
1. A pair of liquid crystal spectacles, comprising:
- a pair of liquid crystal lenses whose refractive indices change when a voltage is applied to the lenses, wherein liquid crystal molecules in the lenses are oriented in a different direction than that in the absence of said voltage;
a frame holding the lenses;
power supply means, contained in the frame, for supplying the voltage to the lenses; and
regulating means for regulating the voltage supplied from the power supply means to the lenses to control the refractive indices of the lenses,said frame including a pair of rims and brows for holding the liquid crystal lenses, a pair of temples swingably attached at one end to the brow, and a pair of ear pieces attached individually to the other ends of the temples, and said regulating means is housed in the temples, each of said temples being formed of a metal pipe for shielding said regulating means from external electrical noise.

Abstract
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.
