According to the principle of photochromic reciprocal reversible reaction, it can quickly darken under sunlight and ultraviolet radiation, fully absorb ultraviolet light, and absorb visible light in a neutral way; Back to the dark place, it can quickly restore colorless transparency. It is mainly used in outdoor, snowy and indoor workplaces with strong light sources to prevent eye damage caused by sunlight, ultraviolet light and glare.
The color changing lens can adjust the color changing depth with the intensity of ultraviolet light. The stronger the ultraviolet light is, the darker the color is. On the contrary, the weaker the ultraviolet light is, the shallower the color will become transparent.The principle is that silver halide particles are added into the lens raw materials, and the silver halide is decomposed into halogen ions and silver ions under the action of ultraviolet light to change color.
