Eye protection protects the eyes from mechanical, chemical, biological, electrical and thermal hazards, but also from weather and radiation-related hazards. Eye protection is often combined with face protection, because the hazards to the eyes can also affect the entire face, or only in this way is effective protection possible. Further information can be found in DGUV regulation 112-992 "Use of eye and face protection". The type of protection required is determined by the risk assessment.
