Abstract: A sport goggle and a system for ventilating a sport goggle is shown and described. The sport goggle has a strap, a lens structure, and a frame having a first edge extending laterally across the wearer's forehead. The first edge is shaped such that a portion of the first edge is curved in a concave up direction when the sport goggle is in a position of use, and such that, when the sport goggle is worn in combination with a helmet, one or more gaps are created between the first edge and a second edge on the front of the helmet. The first edge has a first opening located to allow air to flow into the goggle chamber. Increased goggle ventilation through the first opening can be caused by either the concave up portion of the first edge, or the gaps between the first and second edges.

Abstract: Goggles for protecting the eyes of a wearer in ultra-hazardous conditions. The goggles comprise a frame that seals to the face of the wearer so that the wearer's eyes are enveloped. An adjustable strap is attached to the goggles and goes around the head of the wearer in order to secure the goggles over the wearer's face. Indirect ventilation is utilized to eliminate fogging, and drains are used in the frame to evacuate trapped moisture. A curvilinear lens with multiple optical zones is secured within the frame of the goggles and angled for increased lower peripheral vision. The materials with which the goggles are constructed are capable of withstanding a temperature of at least about 550.degree. F. for a minimum of five minutes without oozing or dripping or otherwise deforming.

Abstract: A goggle is provided with double unitary lenses, separated by an insulating space to reduce fogging. At least one of the lenses is tapered to reduce prismatic distortion through the lens in an as-worn orientation. In an exemplary goggle, the tapering of one lens compensates for prismatic distortion and/or astigmatism introduced by the other of the lenses. The lenses are mounted in a goggle frame in a predetermined orientation with respect to a wearer's normal lines of sight. In one embodiment, the optical centerline or axis of the double lens system is aligned to be parallel with the wearer's normal lines of sight in the as-worn orientation. Method of manufacturing such lenses is also provided. The illustrated goggle defines an enclosed space between the inner lens and the wearer's face when worn, but includes ventilation to the enclosed space to allow moisture to escape.
