Abstract

一种夜间会车眼镜,在夜晚会车时能避免眩光又能看清路面的眼镜。它是由偏振光眼镜中部开一小窗口而制成,1为偏振光镜片2为窗口既可在夜间正常行驶时通过小窗口观察路面,又可在会车时透过偏振光镜片来避免眩光对司机的视线的干扰,能够提高行驶的安全性。

Description

夜间会车眼镜
所属技术领域
本实用新型涉及一种夜晚会车时能避免眩光又能看清路面的眼镜。
背景技术
目前的夜间会车眼镜是采用眼镜片上加一层光栅膜,通过滤去偏振光来防止会车时造成的眩目而能看清路面。但是它有二个缺陷就是(1)由于通过的光线减少50%,在非会车时造成对路面的视线降低;(2)不能看清拐弯车辆远光灯形成的光影,就不能对接近的车提前做出反应,从而影响行车安全。
发明内容
为了解决普通偏振光眼镜在非会车时不能看清路面和拐弯车辆远光灯影的问题,保持原偏振光眼镜会车防眩目的优点,本实用新型在原偏振光眼镜的基础上,在眼镜片的中心开一小窗口。当夜间汽车正常行驶时,透过小窗口观察路面;而当会车时只要将头稍稍一低或一偏(交通规则是靠右行的向右偏,反之向左偏),让对面的车灯透过偏振光镜片即可防眩目。
本实用新型的有益效果是,即可在夜间会车时避免眩光造成的安全隐患,又能在非会车时不降低视线,看清路面和拐弯车辆远光灯形成的光影。
附图说明
附图是平面结构图,附图中1为偏振光镜片,2为窗口。
窗口的形状宜水平方向长形,如水平椭圆形、水平长方形等等,以利于不同瞳距的人使用同种型号的眼镜。
具体实施方式
按附图,偏振光镜片1中部设有一小窗口2。
与偏振光镜片加工方法一样,只是在偏光膜裁剪时多开个小窗口。工艺流程如下:
偏光膜软化处理→弯度加工→表面处理→剪切→合模→浇注→固化→离型→超声清洗→二次固化→检验→磨边→装框→成品入库。
