ABSTRACT:
A unique goggle is disclosed with improved ventilation means. The goggle includes a frame having a transparent lens across its forward side and the frame is secured to the head of the user by a strap or the like. In doing so, a goggle chamber is formed between the frame, lens and the head of the user. At least one ventilation port is formed through the frame which is open to the chamber while an elongated ventilation channel is secured to and extends rearwardly from the frame. One end of the channel is open to the goggle chamber while the other end of the channel is open rearwardly of the goggle frame. In use, air is evacuated from the goggle chamber and out through the ventilation channel by venturi forces.
