Non-vented safety goggles have a flex seal lining around the frame with no external ventilation. This goggle style is well suited for industries that require a lot of movement because they don’t have to worry about unwarranted particles entering the interior of the goggles.
Unlike safety glasses, non-vented safety goggles provide superior protection from liquid splashes, dust, and caustic vapors. In addition, their polycarbonate lens offers clear visibility in all directions, so they don’t limit your peripheral vision.
Because of the adjustable strap, non-vented safety goggles allow prescription eyewear users to wear them comfortably without added irritation. However, due to lack of ventilation, this goggle style tends to fog more frequently than goggles with indirect ventilation.
