Abstract
A goggle has a replaceable lens mounted in a flexible frame containing several large air vents facing forwardly to input external air into the goggle interior. The inlet air vents have converging and angled walls. A first porous foam of particular porosity covers the inlet air vents and is located in an upper air channel with a curved deflector wall to disperse the external air into the interior space. Exit vents located in the bottom of the frame are covered with a second porous foam of different characteristics than the first porous foam. The sides of the goggle frame include curved slots with curved retention bars around which a stretchable headband strap is secured to create uneven load forces on the sides of the goggle frame.
