ABSTRACT:
Ski goggles are composed of goggle frame, goggle lens and rubber band. Vent holes are formed, respectively, in the top peripheral wall portion and the bottom peripheral wall portion of the goggle frame. A permeable coating material is engaged to cover the vent holes. A mounting stand, which serves as duct, is engaged in the central portion of the top peripheral wall portion of the goggle frame. A ventilating fan and a small-size motor for driving the fan are mounted on the mounting stand. The ventilating fan is adapted to compulsorily ventilate the air within the inner space formed between the goggle lens and the face, and is accommodated within the mounting stand. The motor can be turned on or off by a power supply switch. The number of the revolutions can be controlled by the controlling circuit or can be controlled by a controlling circuit or in accordance with the humidity of the inner space.
