APPARATUS AND METHODOLOGY TO MITIGATE FOGGING ON DUAL LENS SPORTS GOGGLE

摘要

A dual pane lens assembly is provided which is adapted to be installed into a frame of a goggle. The dual pane lens assembly may include an outer lens, an inner lens positioned proximate the outer lens, and a gasket disposed between the outer and inner lens which adheres the inner lens to the outer lens, while further forming an air tight semi-annular space between the outer and inner lenses to mitigate against fogging. Dry dehumidified air may be disposed in the semi annular space to further mitigate against fogging. Also, the space between the lenses may be pressurized to a pressure between the atmospheric pressure of the goggle's expected use altitude and the atmospheric pressure of the goggle's assembly altitude such that distortion is minimized when the goggle is worn at the goggle's expected use altitude.
