What is the EN166 Standard?

The EN166 standard is a European norm established by the European Committee for Standardization (CEN) that specifies the safety requirements for personal eye protection. It is widely recognized across Europe and ensures that protective eyewear meets stringent criteria for performance and durability.

EN166 applies to all forms of protective eyewear, including safety glasses, safety goggles, and face shields, making it crucial for PPE: sight. Products that comply with EN166 are tested for protection against conditions such as impact, heat, dust, and chemicals.

Key EN166 Ratings and What They Mean

The EN166 standard uses markings to indicate the level of protection. Here’s a breakdown of the most common symbols:

MarkingMeaningExample Application
1Optical clarity (highest level)Prolonged use, e.g., laboratory work
FLow energy impactWorkshop environments
BMedium energy impactIndustrial tasks involving flying debris
KResistance to surface damage by fine particlesConstruction sites
NAnti-fog coatingCold or humid environments

Why is EN166 Compliance Important?

Using EN166-compliant safety goggles or protective eyewear ensures adherence to European safety standards, offering reliable performance and fostering workplace confidence. 

Choosing EN166-compliant eyewear ensures dependable performance in active environments, protecting against situations like flying debris or chemical exposure. EN166-compliant eyewear helps maintain workplace safety standards and supports legal compliance.

For example, in high-impact settings like construction, properly certified glasses provide peace of mind by effectively protecting against flying debris in challenging environments.

Employers and safety officers must prioritize EN166-compliant products to protect workers effectively. For trusted products, explore our curated range of safety glasses.

How to Choose EN166 Safety Glasses

Selecting EN166-compliant safety glasses involves understanding your specific workplace hazards. This process can begin with a thorough workplace hazard assessment, which involves identifying potential risks, consulting with safety officers, and evaluating past incidents.

Tools such as risk assessment checklists or software solutions tailored to your industry can also be highly effective. Start by identifying the specific challenges in your work environment, such as:

  • Impact: For tasks involving flying debris, look for glasses marked with “F” or “B.”
  • Chemical Exposure: Choose goggles with protection against liquid splashes.
  • Dust and Particles: Opt for sealed eyewear to prevent particle ingress.

To conduct a hazard assessment, consider consulting with a workplace safety officer or using risk assessment tools tailored for your industry. For general guidance on choosing safety glasses, see our main buying guide.

Common Applications of EN166 Safety Glasses

EN166-certified glasses are used across various industries, including:

  • Construction: Protect against flying debris and dust.
  • Laboratory Work: Safeguard against chemical splashes and fine particles.
  • Manufacturing: Ensure your eyes are shielded from sparks, molten metal, and everyday workplace materials.

Additionally, consider related protective equipment such as hearing protectors and hard hats for complete safety coverage.

How to Maintain EN166 Safety Glasses

Proper maintenance ensures the longevity and performance of your safety glasses: Clean them at least once a day, especially in dusty or humid environments, to maintain clarity. Use specific tools like microfiber cloths and non-abrasive cleaning solutions for best results.

  1. Regular Cleaning: Use mild soap and water to remove dirt and grime. Avoid abrasive materials.
  2. Storage: Keep glasses in a protective case to prevent scratches.
  3. Inspection: Regular inspections help ensure your glasses remain in excellent condition for consistent use.

For optimal care, consider cleaning your glasses at least once a day, especially in dusty environments. Investing in anti-fog and scratch-resistant coatings can also enhance durability. Learn about choosing anti-fog options in our anti-fog safety goggles guide.
