ABSTRACT:
A sports goggle includes double lens goggles having inner and outer lenses joined at their perimeter by an adhesive, such as silicone, to form an air cavity. A vent is formed on the outer lens to permit equalization of the air cavity with the environment. The vent includes a plug formed of a water impermeable and gas permeable material. An expansion member may insert within the plug to maintain the plug within the vent. In an alternative embodiment, a rivet having air channels formed therein secures a ring of permeable material to the lens.
