Protective goggles

The model variety of cleanroom safety goggles has increased significantly due to growing importance and regulatory requirements. Typical differentiation criteria are:

Cleanroom protection goggles with direct ventilation
Here the air can reach the lenses inside unhindered, usually from above. A major advantage: the lenses fog up less. Disadvantage: Contamination can escape unhindered via the large openings.

Cleanroom protection goggles with indirect ventilation
With these frame constructions, the air only enters the goggles via "detours". The risk of contamination, e.g. hair or skin scales escaping, is thus significantly lower. However, these goggles often fog up more quickly. But then, when cleaning overhead with detergents or disinfectants, they offer significantly better protection against the unwanted entry of liquids.

Cleanroom protection goggles with anti-fogging equipment
Especially for protection goggles with indirect ventilation, goggles lenses with special coatings against fogging are recommended. However, these lenses with such special options have to be replaced more frequently, as the coatings are affected more quickly by the cleaning, disinfection or sterilisation processes.
