New Material About Photochromic Lens Sun Visor Cap

In the hot summer, an empty sun hat has become an indispensable thing. Therefore, we have developed a new type of sunscreen empty top hat. When the hat is indoors, it is a transparent color. When outdoors, the lens changes color when the hat is exposed to sunlight. As shown below. Whether it is indoors or outdoors, the sun exposure degree of the hat is as high as 100, and the lens is not easy to be scratched and waterproof. If you are interested about it,please contract us for more details.
