Color-changing glasses, also known as "photosensitive lenses". Since the silver halide chemical substance is added to the lens of the color-changing glasses, the originally transparent and colorless lens will become a colored lens for protection when exposed to strong light, so it is suitable for both indoor and outdoor use.

The color-changing glasses are made of optical glass containing silver halide crystallites. According to the principle of the reversible reaction of light and color, it can quickly darken under the irradiation of sunlight and ultraviolet rays, completely absorb ultraviolet rays, and neutrally absorb visible light back to darkness, which can quickly restore colorless and transparent.

Color-changing glasses are mainly used in outdoor, snowy and indoor workplaces with strong light sources to prevent the eyes from being damaged by sunlight, ultraviolet rays and glare.

In layman's terms, under strong light, the silver halide inside turns into black silver particles under the light.

When choosing color-changing glasses, the main considerations are the functional characteristics of the lenses, the use of glasses, personal color requirements, and so on. Photochromic lenses can also be made into a variety of colors, such as gray, brown and so on.

The gray lens of the color changing glasses can absorb infrared rays and 98 ultraviolet rays. The advantage of the gray lens is that it will not change the original color of the scene because of the lens, and it is satisfied that it can effectively reduce the light intensity.

The pink lens of the color-changing glasses can absorb 95 ultraviolet rays. If used as glasses for correcting vision, women who wear them often choose reddish lenses, because reddish lenses have better UV absorption and can reduce the overall light intensity, and the wearer will feel comfortable.

Brown lenses can absorb ultraviolet rays and can filter out a large amount of blue light, which can improve visual contrast and clarity, so they are very popular with wearers.
