What is the difference between a vented, indirect vent and non-vented goggle?
A vented goggle has open ports on each side of the goggle for ventilation. Vented goggles are typically used for impact hazards, not chemical splash or vapor. Indirect vented goggles provide protection from splash by a covered vent that allows for air movement but prevents liquid from going directly in the goggle. Non-vented goggles have no venting of any kid and offer protection from dust, mist, liquid and vapors.
