FAQ
– Do the glasses fog up when wearing a face mask? — Choose the AF (anti-fog) version.
– Can safety glasses replace a face shield? — Not for forceful chemical splashes; use a face shield.
Material: why are safety lenses made of polycarbonate?
Most industrial safety eyewear (3M SecureFit SF400, 3M 1621 goggles…) uses polycarbonate (PC) for both lens and frame: lightweight (the SF400 series weighs about 19 g) and far more impact resistant than glass or acrylic lenses. PC is softer than glass, so lenses are usually given additional coatings:
- Hard anti-scratch coating (marking K under EN 166).
- Anti-fog coating (marking N under EN 166, X under ANSI Z87.1-2020) — only on versions with the AF suffix, not on every model.
- UV filtering: the clear SF400 lens meets the UV filter requirements of EN 170 (marking 2C-1.2).
Reading ANSI Z87.1 markings (US standard)
| Marking | Meaning |
|---|---|
| Z87 | Meets basic optical requirements only, not rated for high impact |
| Z87+ | Passes high-impact testing: a 500 g pointed projectile dropped from a minimum height of 4 ft (about 1.2 m); steel ball fired at 102 mph (about 45 m/s) for spectacles, 250 mph (about 112 m/s) for goggles |
| D3 / D4 / D5 | Protection against liquid splash / dust / fine dust |
| U2–U6 | UV filter rating, U6 highest |
| X | Passes anti-fog testing (added in the 2020 edition) |
Reading EN 166 markings (European standard)
- Optical class 1: can be worn all day without eye strain (classes 2 and 3 for short-term use).
- Impact: F = particles at 45 m/s (all eyewear types); B = 120 m/s (goggles and face shields only); A = 190 m/s (face shields only). The letter T after F/B/A: impact tested at −5 °C and +55 °C.
- Field of use (marked on the frame): 3 = liquid droplets and splashes; 4 = large dust particles; 5 = gas and fine dust; 9 = molten metal.
- Example: the 3M SF401AF lens is marked “2C-1.2 3M 1 FT KN”: UV filter, optical class 1, low-energy impact at extreme temperatures, anti-scratch, anti-fog.
Spectacles or goggles?
Under EN 166, spectacles cannot be tested for protection against liquid splash and large dust particles — only goggles can carry markings 3, 4, 5. 3M documentation for the SF400 series states clearly: not tested against liquid droplets, not for use in grinding or welding, not designed to be worn over prescription glasses. Therefore:
- Mixing chemicals, pouring solvents, chemical cleaning → indirect-vent goggles (3M 1621): the vents are covered, so air circulates but splashes cannot enter directly; can be worn over prescription glasses.
- Grinding, cutting with heavy spatter → goggles combined with a face shield.
- Assembly, inspection, warehouse, machine operation → lightweight anti-fog spectacles, worn for the whole shift.
Cleaning and replacement
- Rinse with clean water before wiping to wash away hard dust particles, then wipe with a soft cloth; wiping dust off dry easily scratches the coating.
- Do not clean with strong solvents (acetone, petrol) — they damage the coating and cloud the polycarbonate.
- Store in a pouch or case; do not place the glasses lens-down on the bench.
- Replace the eyewear when the lenses are scratched enough to impair vision, cracked, the anti-fog coating is peeling, the frame is loose, or after a heavy impact.
Common mistakes
- Treating ordinary prescription glasses or sunglasses as safety eyewear — they are not impact tested to any standard.
- Using spectacles at chemical mixing stations.
- Using dark glasses in poorly lit workshops — reduces visibility and increases the risk of accidents.
