Why does the lens fog up?

In colder environments, the air is significantly drier. When the lens comes in contact with hot air, there is more moisture in the hot air. When it comes into contact with cold lenses, a condensation effect will occur, forming fine crystals on the lens surface, which will cause the lens to fog.

This phenomenon is generally not dangerous, but be careful when driving the door. Because the air conditioner is usually turned on in the summer, fogging easily occurs. In winter, the windows are tightly closed, and the temperature is also different from the outdoor temperature. When opening the door, pay attention to safety.
