EN 166 Rated Safety Glasses
The EN 166 Personal Eye Protection European Standard indicates that a style of eyewear has passed industrial and technical safety tests. There are several levels of civilian eye protection including EN.166S, EN.166F and EN 167:2001 eyewear. These categories of safety glasses provide increasing levels of impact protection. Standard EN.166B applies to safety goggles.

If you live or work in Europe or for a European company, you may need EN 166 rated safety glasses. The same eyewear may also meet other international standards such as the American National Standards Institute Z87.1 standard or the Canadian Standards Association Z94.3 standard.
