Your Guide to Eye Protection

Protective Clothing Series | Eye Protection

Personal Protective Equipment is paramount when it comes to eye protection. Eye protection should be worn when a potential risk to your eyes has been identified in your workplace. Risk to your eyes is common in many industries, particularly those of you who work in construction, manufacturing, automotive and healthcare. A large percentage of eye injuries that happen in the workplace could be prevented if you are wearing the correct protective eye wear.

“Construction has a much higher rate of eye injuries than any other industry


EN 166

EN 166 is the European technical standard that all safety eye protection must comply with. The main tests that safety glasses undergo in this standard are Optical Requirements and Impact Resistance/Mechanical Protection. There are some optional tests that EN 166 may include: Protection against High Speed Objects and Protection against Extreme Temperatures (ranging from -5°c to +55°c).

The results of these tests then define the optical class and mechanical protection rating that the eye protection will receive.

Optical Tolerance Power

Optical Class


± 0.06 Dioptres


Distortion Free - Work all the time

± 0.12 Dioptres


Medium Quality - Work occasionally

± 0.25 Dioptres


Work Briefly – Exceptional use

 Dioptre = a unit of measurement of the optical power of a lens


Mechanical Protection


Minimal Impact Resistance


Low Energy Impact


Medium Energy Impact


High Energy Impact
