ABSTRACT:
A flexible mask goggle is presented comprising a flexible housing which receives an optically transparent lens. The housing includes a novel ventilation structure along the upper and lower surfaces thereof. On the upper surface, this ventilation structure comprises an array of spaced slots while the ventilation structure on the lower surface comprises two spaced groups containing similar spaced slots. Both the upper and lower vents permit direct airflow in and out of the goggle. In an important feature of the present invention, removable caps are snap locked over the upper and lower ventilation structure. These caps convert the otherwise direct airflow through the vents to an indirect airflow.
