Color-changing anti-blue glasses are a combination of color-changing lenses and anti-blue glasses.
Color-changing principle: Special light-sensitive color-changing materials, such as silver halide, are added to the lens. When exposed to light of different intensities or wavelengths, these materials undergo chemical reactions that cause the lens to change color. For example, in indoor or low-light environments, the lens color is lighter or transparent; When exposed to sunlight or strong light, the photochromic material is stimulated and the lens color darkens.
It can effectively block the damage of blue light to the eyes, and automatically adjust the color of the lens according to the change of environmental light, adapt to different light conditions, and reduce the discomfort of eye fatigue, dryness and other symptoms.
