<p>A sports goggle provided with power means in the form of a miniature electrical fan mounted within the air space defined by the goggle and the face of the wearer when the goggle is in place. The fan is selectively actuatable by the wearer of the goggle to draw the warm humid air within the air space into the fan, to compress the same therein, and to circulate the same throughout the air space to prevent condensation build-up on the inner surface of the lens structure of the goggle and on eyeglasses of the wearer of the goggle. The fan also urges the circulated warm humid air outwardly of the goggle through air passages provided in the shell of the goggle so that ambient air may enter the goggle to replace the forced out air without admitting snow or other precipitation from the ambient.</p> |
