Abstract
Goggles and eyeglasses worn in winter weather conditions are subject to fogging. A method of preventing condensation from forming on goggles and on eyeglasses worn under goggles is provided. The method involves using a fan to exhaust air from the air space between the goggles and a user's face. Continuous operation of the fan is designed to be inaudible and effective to prevent fogging. The method can involve use of a goggle ventilation design which improves wearer comfort. The goggle can also clear fogging which has occurred while the fan is not in operation.
