Important to know

In many work situations, it is necessary to give the eye protection in the form of goggles or a visor. The slightest thorn in the side of the eye, flying particles, dangerous liquids, dust, etc. can otherwise have serious consequences. It is therefore important to choose equipment that is suitable for the work environment and the task. Goggles or equivalent eye protection should be worn when you are at risk of particles or splashes in the eyes, and when you are at risk of radiation or strong light.

In order to be able to safely choose the right protection, it is important to find out what risks exist in the surrounding environment and that you are careful that the protection is adapted to the person who is to wear it.

Important to know about eye & face protection

Eye protection and visors are used to protect against risks to the eyes and face. These risks can be mechanical, e.g. flying particles, chemical e.g. splashes of chemicals or infectious particles, e.g. virus.

Different types of protection

There are several types of eye and face protection.

  • Glasses with or without side protection. Side protection is required to prevent particles from entering the eyes.
  • Basket glasses that have a full-coverage frame and close tightly around the eyes. Suitable for use when at risk of chemicals or in an environment with a lot of particles.
  • Visor or hood, sometimes combined with a helmet or respirator. These are mainly used in environments where both eyes and face are to be protected.

If there is a risk of splashes of chemicals, use a visor, hood with visor or basket glasses that close tightly to the face. To be completely protected, it is required that it has the right fit and that you use the right protection for the task.


Because there are different levels of protection, each eye protection has a marking on the lens and frame. This label shows what the eye protection protects against. The marking is coded and an explanation of the codes can always be found in the operating instructions. The frame must be marked with the manufacturer's symbol, number of the standard that is followed and symbol for mechanical strength. Sometimes there is also a symbol for the area of ​​use. The lens must be marked with a filter, the degree of density of the lens, the manufacturer's symbol, optical class and a symbol for mechanical strength. The picture below picture explains how the label works.

[a] Manufacturer

[b] Number of EN standard

[c] Applicable uses
  No marking = basic use [glasses]
     3 = Liquids [basket glasses, visor]
     4 = Dust particles> 5um [basket glasses]
     5 = Glass and small dust particles <5um [basket glasses]
     8 = Short circuit electric arcs [visor]
     9 = Molten metal and hot substances [basket glasses, visor]

[d] Mechanical resistance
     S = Reinforced strength
     F = High speed, low energy stop (6 mm steel ball at 45 m/s)
     B = High speed, medium energy stop (6 mm steel ball at 120 m/s)
     A = High speed, high energy stop (6 mm steel ball at 190 m/s)
    Marking “T” after the symbol for mechanical resistance indicates protection     at extreme temperatures (FT, BT, AT)

[H] = adapted for small head shape

[F] = Highest hue number compatible with the frame
