EN 166 Requirements

EN 166, the international standard for personal eye-protection specifications, clearly outlines three unambiguous optical requirements:

7.1.5.2 Resistance to ultraviolet radiation
7.3.1    Resistance to surface damage by fine particles
7.3.2    Resistance to fogging

Unlike alternative anti-fog treatments, FSI Visgard technology meets these EN 166 requirements.

Visgard is particularly well-suited for abrasion resistance (7.3.1) because the surface is elastic rather than hard and brittle, as are most other abrasion-esistant coatings. When abraded, a Visgard surface will deform, then recover immediately, so the coating will not crack, flake or peel when flexed.

While no coating can prevent condensation, Visgard will cause the water droplets to spread out to a clear film that does not distort vision. Visgard-treated surfaces will remain fog-free indefinitely (7.3.2).

EN 166 also details the type of information manufacturers must include on their eye-protection products, including:

• Eye-protectors
• Replacement oculars
• Replacement frames

• The name and address of the manufacturer
• The number of the standard
• The eye-protector model identification
• Instructions for storage, use and maintenance
• A warning that scratched or damaged oculars should be replaced

This clause outlines 16 required pieces of information in all. The presence of these items is a useful indication to purchasers that a manufacturer is credible, reliable and up-to-date on technical standards.
