偏光镜是黑色的。
偏光眼镜是户外活动不可缺少的装备和装扮之一，它让我们的户外活动更加的顺畅和便利。经常接触到的太阳光带来的紫外线，而实际伤害眼睛的大部分紫外线是来自地球表面的反射光。
在这种情况下，佩戴品质良好的太阳镜片是保护眼睛的最佳方法。太阳镜片的颜色对光线的投射和吸收程度不同，们可以根据我们的需要选择不同颜色的镜片。
扩展资料：
偏光太阳镜提供了另外一种保护眼睛的机理。柏油路的反射光是比较特殊的偏振光。这种反射光与直接来自太阳的光或者任何人工光源的光的不同之自就在于秩序问题。偏振光是由全朝一个方向震动的波形成的，而一般的光则是由不定向震动的波形成的。
这就像一群无秩序随意走动的人与一批迈着整齐步伐行进的士兵那样，形成了鲜明的对比。一般地讲，反射光是一种有秩序的光。
偏光镜片在阻挡这种光时特别有效，因为它的过滤性在发挥作用。这种镜片只让朝一定方向震动的偏振波通过，就像将光“梳理”了一样。对于道路反光问题，使用偏光太阳镜能减少光的透射，因为它不让与道路平行震动的光波通过。

偏光眼镜镜片有各种颜色，不同颜色作用也不同：
灰色：对任何色谱都能均衡吸收,因此观看景物只会变暗,但不会有明显色差,展现真实自然感觉,属于中性色系。
蓝灰：与灰色眼镜片相似,同属于中性镜片,但颜色更深,可见光吸收率更高。
茶色：滤除大量蓝光,可以改善视觉对比度和清晰度,在空气污染严重或者多雾情况下配戴效果较好。
绿色：在吸收光线同时,能最大限度地增加到达眼睛的绿色光,所以有令人凉爽舒适的感觉,适合眼睛容易疲劳的人使用。
水银：镜片表面采用高密度的镜面镀膜,这样的眼镜片能更多地吸入、反射可见光,适合户外运动人士。
黄色：严格地说,此类镜片不属于太阳镜片,因为其几乎不能阻挡和减少可见光,但在多雾和黄昏的时候,黄色镜片可以提高对比度,提供更准确的视像。所以,黄色眼镜片又称为夜视镜,也有很多年轻人配戴黄色太阳眼镜作为户外运动装饰使用。
浅蓝色、浅粉红：浅蓝色、浅粉红太阳镜同样是装饰性多于实用性的镜片。
灰色：对任何色谱都能均衡吸收,因此观看景物只会变暗,但不会有明显色差,展现真实自然感觉,属于中性色系。

Gray: The most popular color for sunglasses in the U.S., gray transmits all colors evenly. It makes a good everyday or all-purpose choice of sunglasses. It is recommended for ocean fishing, where the water tends to be blue. "Classic gray" is a color that provides near-natural vision and true color perception.
Brown: Because brown improves contrast and depth perception, it is best for driving and shallow-water fishing. Light brown is a good color for overcast days and is recommended for skiers and golfers. Brown is another popular color, especially among the fashion-conscious, because many fashion authorities believe that brown is flattering to the face.
Red: Red is primarily used by sportsmen working in bright, sunny places.
Orange:Like yellow, orange lenses filter out blue light and increase contrast sensitivity. Orange is a popular color among skeet shooters because it makes the targets more visible.
Yellow: This color filters out blue light. Because it provides the highest level of contrast, it is perfect for cloudy-day driving and for marksmanship practise.
Green: Green improves contrast slightly, and keeps a good balance among the colors of light. It is a popular color for tennis, golf, or driving.
Blue: Blue allows the most blue light to filter through, so it is good in partly cloudy weather. Blue is a popular lens color among tennis players and golfers.
Violet: Violet causes green to fade and enhances orange, green, and black. It is good for shooting under average conditions.
Copper: Copper provides maximum contrast and is best for any activity in which good vision is important.
Brown: Because brown improves contrast and depth perception, it is best for driving and shallow-water fishing. Light brown is a good color for overcast days and is recommended for skiers and golfers.
