The weather is getting cold, can glasses change color?

Smart color-changing glasses will also change color on cloudy days.

At present, many color-changing factors on smart color-changing glasses change color according to the intensity of ultraviolet light.

Although there is no sunshine on cloudy days, it does not mean that ultraviolet rays do not exist. If there is ultraviolet light, the smart color-changing lens will change color, but the depth of color change is different.

The color-changing lens is irradiated by ultraviolet rays and short-wave visible light in the sun, the color becomes darker and the light transmittance decreases; When the lens is indoors or in the dark, the light transmittance increases, and the color becomes lighter and brighter. Its color-changing performance is inversely proportional to the heat energy obtained, and the lens will become transparent in hot or warm environment. All-sight _ photochromic lens is the best photochromic lens under all temperature conditions. Full field _ lenses can be automatically replaced, providing convenience, comfort and protection.
