The air pressure difference generated during riding will suck water vapor out of the helmet. This method is much cheaper and simpler than the previous method. Spray a layer of anti fogging agent on the helmet lens. The effect is good, but it is troublesome to spray it often.

3. Use design methods to control the airflow direction in the helmet. When riding in winter, in order to ensure the temperature inside the helmet, the water vapor inside the helmet is quickly discharged out of the helmet, reducing the humidity inside the helmet, so as to achieve the anti fog effect. A small hole can be opened on the motorcycle helmet: when the motorcycle is running, the mirror on the motorcycle helmet can slightly lift a small hole. The larger the opening, the better the effect of preventing the helmet from fogging.
