Eyes & Face Protection
Face protection is essential in workplaces where a worker's face is exposed to multiple risks. Both mechanical and chemical exposure and radiation can cause serious injury, from eye irritation to eye inflammation to blindness. Eye protection products from DACH make an important contribution to preventing such damage.
Requirements for personal eye protection: DIN EN 166
This standard specifies requirements and markings for different types of personal eye protection equipment. Prismatic, spherical and astigmatic refractive indices are tested in order to ensure the required vision for the particular work operation.
Ranges of use of protective eyewear
Compliant with the above refractive indices, lenses are divided into the following classes:
- Class 1: for continuous use (e.g. when working under high optical requirements).
- Class 2: for occasional use (e.g. work with medium visual requirements).
- Class 3: for infrequent use (e.g. for rough work requiring visual protection in exceptional cases).
Mechanical strength of protective eyewear and visors:
Eye protection devices usually have a marking:
Labelling | Danger |
without | minimum strength (filter only) |
S | Increased strength (filters only) |
F | Low energy impact (45 m/s) |
B | Medium energy shock (120 m/s) |
A | high energy impact (190 m/s) |
Labelling of protective eyewear
The labelling of protective eyewear shall include:
- Manufacturer's identification mark
- Number of EN standard
- Ranges of use
- Short sign for resistance to particles
