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, I will tell you where to buy them, how to choose wisely, and what to ask the supplier so you don't make a mistake.
Who sells safety glasses with anti-fog treatment > 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 supplies: ideal for quick replacement and local purchases.
Online shops specialising in occupational safety: extensive catalogue, technical data sheets and fast delivery.
Direct from brand/manufacturer: useful for large-scale projects, approvals and product training.
Practical tip: look for lenses with specific ‘anti-fog / AF’ and, if possible, marked ‘N’ (EN 166) which guarantees anti-fog performance.
Key factors when choosing anti-fog glasses for professional use
Type of glasses
- Sealed goggles/indirect ventilation: better barrier against liquids and dust.
- Wrap-around glasses: lightweight and compatible with helmets/ear muffs.
- OTG (Over-The-Glass): designed to be worn over prescription glasses.
- Anti-fog treatment
Check for permanent AF coating (not just ‘wipes’ or sprays).
- Ask about wash resistance and compatibility with disinfectants.
- Scratch resistance (HC)
- Hard coat extends service life, especially in dusty environments and with frequent handling.
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 neutral soap; avoid solvents.
- Store in a case to preserve the AF coating.
Typical uses
- Food and beverages / industrial cleaning (washdown, steam, disinfectants)
- Laboratories and pharmaceuticals (temperature changes, splashes)
- Construction and woodworking (dust + mask = constant fogging)
- Metalworking (grinding/polishing; add face shield if there is intense projection)
- Agriculture and chemicals (mists, phytosanitary products; always consult the product data sheet)
Checklist for shopping without surprises
Indicate environment (temperature/humidity) and combined PPE (mask).
Request anti-fog testing (marked N or test documentation).
Confirm replacement and spare parts policies (elastic bands, foam).
Verify delivery times and stock in sizes/models.
Request samples to test with your team if it is a large purchase.
