ABSTRACT:
A ventilation adjustment assembly is provided for a goggle having a ventilated lens mounted in a frame. In one embodiment, the lens has one or more ventilation apertures forming a linear or curved path. An elongated shutter housing is formed by a base having pair of parallel sidewalls or spacers mounted on the lens on opposite sides of and in close proximity to the path of lens apertures. One or more apertures on the base align with the lens apertures. An elongated shutter is slidably disposed in the shutter housing. The shutter has one or more apertures which are alignable with apertures in the base and lens. By sliding the shutter within its housing, ventilation air flow is regulated as the shutter apertures move in and out of alignment with the base and lens apertures.
