Abstract
An air injection sports goggle (10) has a lens subframe (14) connected to a face flange subframe (16) by struts (18). The struts (18) form a top opening (20) and a pair of cheek openings (22) between the lens subframe (14) and the face flange subframe (16). A lens (24) is contained in the lens subframe (14). A cover fits (46) over the top opening (20). A pair of open cell foam vents (52) are located in the pair of cheek openings (22). An air injection hole (54) provides access between an outside and an interior space. A ventilating fan (12) located in the top opening (20) pulls air in through the air injection hole (54) and the pair of cheek openings (22) and exhausts the air through the top opening (20).
