    Color-changing anti-blue reading glasses are a combination of color-changing lenses and anti-blue reading glasses.
    Color-changing function: Chemicals such as silver halide are added to the lens, and the structure of these substances will change under different lighting conditions, thus changing the color of the lens. For example, in outdoor bright light, the silver halide in the lens will break down into silver atoms and halogen atoms, silver atoms together to make the lens color darker, blocking too much light into the eye; After entering the room, the light becomes weaker, the silver halide recombines, and the lens returns to transparency.
    Anti-blue light function: By coating the lens surface or adding special materials, the blue light emitted by the electronic device screen can be selectively absorbed or reflected. For example, some lenses can block harmful blue light in the 400-450nm band, reduce the damage of blue light to the retina of the eye, and alleviate the discomfort symptoms such as eye fatigue, dryness, and acid swelling caused by long-term use of electronic devices.
