When you work in environments with temperature changes, high humidity, or combined use with a mask/respirator, anti-fog (AF) is no longer a “plus”: it is a safety requirement. In this guide, we will explain where to buy them, how to choose them, and what to ask the supplier so you don't make a mistake.
Who sells safety glasses with anti-fog coating> Where to buy them (reliable B2B channels)
- PPE distributors (wholesalers/industrial retailers): they offer professional brands, stable stock and technical advice.
- Technical hardware stores and industrial suppliers: ideal for a quick replacement and local purchases.
- Online shops specialized in work safety: large catalogue, technical data sheets and fast delivery.
- Direct from the brand/manufacturer: useful for large-volume projects, certifications, and product development.
Practical tip: look for lenses with specific ‘anti-fog / AF’ and, if possible, marked ‘N’ (EN 166) which guarantees anti-fog
Key points to keep in mind when choosing anti-fog safety glasses for professional use.
Type of glasses
- Sealed glasses/indirect ventilation: better protection against liquids and dust.
- Wrap-around glasses: lightweight and compatible with helmets/earmuffs
- OTG (Over-The-Glass): designed to be worn over prescription glasses.
Anti-fog coating.
- Verify that it is an Anti-fog coating ( not just wipes or sprays)
- Ask about their wash resistance and its compatibility with disinfectants.
Scratch resistance (HC)
- Hard coat extends their time use, , especially in dust environments and frequent use.
Compatibility with other PPE
- Check seal with respirators, fit with helmet and ear muffs.
Regulations and marking
- EN 166 (general requirements) and marking N (anti-fog), K (anti-scratch).
- Filter according to use: colourless (indoors), solar EN 172 (outdoors), amber/copper (improves contrast).
Maintenance
- Clean with warm water and mild soap; avoid solvents.
- Store in a protective case to preserve the AF coating.
Typical uses
- Food and beverages / industrial cleaning (washdown, steam, sanitizers)
- Laboratories and pharmaceuticals (temperature changes, splashes)
- Construction and woodworking (dust + mask = constant fog)
- Metal (grinding/polishing; add face shield if there is intense projection)
- Agriculture and chemicals (mists, phytosanitary products; always check the product data sheet)
Shopping checklist to avoid surprises
- Inform about Work environment (temperature/humidity) and if combined with other PPE (mask/helmet).
- Request for an anti-fog testing (marked N or test documentation).
- Confirm replacement and spare parts policies (elastic bands, foam).
- Verify delivery times and sizes/models stocks.
- Request samples to test with your team if it is a big purchase.
