Venting of the eye cavity of the sport goggle is aided by forming of the goggle body shape to create low pressure zones adjacent to side and top venting apertures that communicate with the eye cavity. During use by a user, forward motion creates air flow through the focusing channel thereby increasing the air pressure entering the goggle through intake apertures and the curved shape of the goggle body creates low pressure zones adjacent to venting apertures to pull air from the eye cavity thereby increasing air flow and eliminating fogging. Additional utility is provided by aperture gates that are cooperatively engageable with the venting apertures to regulate air flow and/or absorb moisture.Field of SearchBy ventilation of shieldWith forced air circulator Via tortuous air path Detachable lens-mounting Having frame for each eye Suspended within a goggle Connected at center By nose-rest With seal for face Included in shield for eyes With seal (e.g., cup) for each eye Having unitary frame Having antifog shield or lens | |
