FAQs
What type of protection do these glasses offer?
These glasses offer protection against low-impact particles and fragments (EN 166 1 FT standard), and feature anti-scratch (K) and anti-fog (N) coatings for enhanced visibility and durability.
Are these glasses suitable for welding?
No, these are general-purpose safety glasses with clear lenses. They are not designed for welding and do not provide protection against UV or IR radiation associated with welding processes.
Can I wear these over my prescription glasses?
These glasses are designed as standalone safety eyewear and may not comfortably fit over most prescription glasses. It is recommended to check the dimensions or consider dedicated over-prescription safety glasses.
How should I clean the lenses to preserve the coatings?
Clean lenses using a soft, damp cloth or lens-specific cleaning wipes. Avoid using paper towels, tissues, or abrasive cleaners, as these can damage the anti-scratch and anti-fog treatments.
What does 'KN certified' mean?
'K' certified means the lenses have a high-level anti-scratch treatment. 'N' certified means the lenses have a high-level anti-fog treatment.
Are these glasses adjustable?
The glasses feature co-injected, dual-color, and extremely flexible temples for comfort and a secure fit. The soft TPR nose piece also offers a universal fit. While not directly adjustable, the flexibility allows for a good fit on many users.
What standards do these safety glasses meet?
They meet EN 166 1 FT (impact resistance, K anti-scratch, N anti-fog), EN 170 2C-1.2 (UV filters), and EN 172 5-3.1 (sunglasses for industrial use) standards. They are also CE and UKCA marked.
Troubleshooting
Lenses fog up excessively.
Ensure the anti-fog coating is intact. Clean lenses gently with a soft cloth. If fogging persists, consider a different model with enhanced anti-fog features or ensure the glasses fit snugly to allow minimal air ingress.
Glasses slip down the nose.
Adjust the nose piece for a snugger fit. Ensure the arms are properly positioned over the ears. The flexible arms can be gently molded for a better fit, but avoid excessive force.
Scratches appear on lenses.
Avoid wiping lenses with dry or abrasive cloths. Store glasses in a protective case. If significant scratches impair vision, replace the glasses.
Discomfort during prolonged wear.
Ensure the glasses are not too tight. The lightweight design should minimize pressure, but individual facial structures vary. Gently adjust the arms for a more comfortable fit.
