Abstract
A goggle has a replaceable plastic lens mounted in a flexible frame containing several air vents for passing external air through the goggle interior. The lens is formed of thermoplastic materials to provide spherical and cylindrical versions of the lens. The thermoplastic resins incorporate dyes which tint the lens to create a transmission curve with a broad flattened peak above a 50% transmission level and steep slopes to couple with the response characteristics of the rods of the human eye retina so as to improve contrast in very low light conditions such as night skiing under artificial light. Inlet and outlet air vents are covered by porous foam to reduce fogging in an outdoor environment.
