Abstract

Abstract A ventilated goggle having a face piece with a front wall, a top wall, a bottom wall, and side walls. The front wall is defined by a pair of laterally spaced wall sections that are substantially parallel to each other with each having an aligned aperture therein to allow the wearer to see therethrough. The open space between the laterally spaced wall sections form a channel that extends around the inner surface of the front wall and a plurality of spaced locking lugs are formed integrally with the outer walls of said face piece such that they project inwardly into said channel. The goggles have a single lens which is detachably positioned in said channel and the lens comprises a substantially planar central body shaped like the letter B laying on its side and has a plurality of spacers positioned at intervals around its periphery. The spacers are of a thickness greater than the thickness of the central body with that thickness extending laterally outwardly from both sides of the central body. The peripheral edge of the central body between the spacers is recessed inwardly from the peripheral edge of the spacers to form ventilation paths between the spacers when the lens is mounted in the channel.
