ABSTRACT:
An anti-fog goggle is provided having a foam frame with a method of manufacturing the goggle. The goggle is composed of generally planar individual members, yet the goggle has a desired degree of self-supporting curvature. The anti-fog goggle has a semi-rigid support member for supporting the goggle's lens, the support member being stamped out of a planar sheet of foam. The foam support member has air channels depressed therein through which air enters and exits the interior of the goggle to prevent condensation from forming on the viewing surface of the lens' interior. The lens is stamped from a planar sheet of transparent plastic which is deformable into a simple curve. The lens is formed with a plurality of apertures therein which are aligned with air channels in the support member when the lends is secured thereto. The lens' apertures form ports through which air may flow into the air channels, the air channels directing the air downward across the inner surface of the lens. To make the goggle, the support member is curved about a form having the generally desired curvature and the lens adhered to the curved support member with an adhesive to deform the lens and support member into the form curvature which is substantially maintained when the lens and support member are removed from the form. The goggle may also include a cushioning foam member which is adhered to the inner surface of the semi-rigid foam support member to cushion contact with the wearer's face.
