Eye protection at work: which safety glasses suit the task?

Why is eye protection important?

Flying particles, dust, chemicals, liquid splashes, UV radiation and light generated during welding can all pose a risk to the eyes. When choosing suitable protective equipment, the specific work process and workplace risk assessment should always be the basis.

Main types of eye and face protection

Open-design safety glasses

Safety glasses with impact-resistant lenses are a good choice for flying particles, debris and general mechanical risks. As they do not fully seal around the sides, enclosed protection is required against dust, vapours or splashing liquids.

Safety goggles

Safety goggles provide more enclosed protection around the eyes and may therefore be appropriate for dusty work or tasks involving splashes or chemicals. Always check suitability based on the product marking and the manufacturer’s instructions.

Face shield

A face shield covers a larger area of the face, but on its own it does not replace safety glasses for every hazard. For splashes, sparks or welding, combined protection is often required, together with the appropriate filter shade.

What do the EN 166 markings mean?

Markings under EN 166 provide information about the optical properties, mechanical strength and special applications of protective equipment. Always interpret the marking together with the documentation supplied with the product; the different symbols do not represent general hazard categories.

Practical tips for use

• Choose a design that matches the work process and the workplace risk assessment.
• Check the condition of the lens, frame and strap before every use.
• Replace scratched, cracked or heavily clouded lenses.
• Anti-fog and scratch-resistant coatings can only perform properly if the product is cleaned in accordance with the manufacturer’s instructions.
• Store eye protection clean, preferably in a case or protected location.
