Abstract
A goggle frame includes air vents spaced along its periphery and covered with a fibrous lining to vent the goggle interior while preventing entry of foreign matter. A detachable partial-face shield has snap-in posts which mate with apertures spaced along a bottom rim of the goggle frame. When the shield is attached to the rim, a shield nose section rests on a nose bridge of the frame, and shield side sections curve behind adjacent air vents in the frame to force frontal air therethrough. A main lens has locking projections received in a peripheral groove around the frame. One or more auxiliary lenses have edge regions received in the same peripheral groove, each auxiliary lens having an offset tab to allow a wearer to detach the auxiliary lens while the goggle is being worn.
