The present invention discloses a helmet lens demister, also including the lens (e.g., a snow or wind goggle) if being used independently. The helmet lens demister includes primarily a socket, a power supply device, a fan and fixing devices by which the demister is fixed on a predetermined location for defogging the lens. When defogging, a controller activates the power supply device to produce electricity and drive the fan. Then, the fan produces wind power to cause air convection. Therefore, a temperature in an inner space of the helmet lens will be close to a temperature of ambient environment and a temperature and humidity on an inner side of the lens can be adjusted; therefore, water molecules will not be attached on a side of the lens close to a human body. Moreover, as an entire structure is simple, the socket can be fixed freely, to improve the practicability.
