Optically corrected goggle |
摘要 |
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.
