Abstract	本发明涉及一种激光防护眼镜，其包括：镜片和光控电路；所述镜片包含聚合物稳定液晶，所述光控电路连接所述聚合物稳定液晶的两端；所述光控电路能够感应激光强度，并根据激光强度自动调节施加在所述聚合物稳定液晶两端的电压，使所述聚合物稳定液晶在透明态和散射态之间切换，借此调节所述镜片的透过率，在激光强度超过安全强度范围时，所述光控电路施加在所述聚合物稳定液晶两端的电压增大，所述聚合物稳定液晶立即变成散射态，致使镜片的透过率迅速下降，对佩戴者的眼睛起到防护作用。本发明提供的激光防滑眼镜，响应时间在5ms内，可提供对使用者眼部的高强激光快速防护作用。
Other Abstract	The invention relates to a pair of laser protective glasses. The pair of laser protective glasses comprises lenses and a light-operated circuit. The lens comprises polymer stabilized liquid crystal, and the light-operated circuit is connected with two ends of the polymer stabilized liquid crystal; the light-operated circuit can sense the laser intensity and automatically adjust the voltage applied to the two ends of the polymer stabilized liquid crystal according to the laser intensity, so that the polymer stabilized liquid crystal is switched between a transparent state and a scattering state, the transmittance of the lens is adjusted, and when the laser intensity exceeds a safe intensity range, the voltage applied to the two ends of the polymer stabilized liquid crystal by the light-operated circuit is increased, and the polymer stabilized liquid crystal is immediately changed into a scattering state, so that the transmittance of the lens is quickly reduced, and the eyes of the wearer are protected. The laser anti-slip glasses provided by the invention have response time within 5ms, and can provide a high-intensity laser rapid protection effect on eyes of a user.
