When it comes to workplace safety, eye protection is non-negotiable. But if your safety glasses fog up, they’re not just annoying—they're dangerous. Foggy lenses impair your vision, increase the risk of accidents, and often lead workers to remove their eyewear altogether, which defeats the purpose.
At Novarlo, we’re all about maximizing your protection and your performance. In this guide, we’ll cover how to prevent lens fogging and break down the different types of safety eyewear—so you can choose the right protection for the job and keep it crystal clear.
Why Do Safety Glasses Fog Up?
Fogging is caused by condensation—tiny water droplets forming when warm, moist air (like your breath or sweat) hits a cooler surface (like your lenses). It’s especially common in:
- Hot or humid environments
- When wearing masks or respirators
- High-exertion tasks that increase body heat
- Cold weather job sites
5 Ways to Prevent Fogging
-
Use Anti-Fog Coated Glasses
Many modern safety glasses feature built-in anti-fog coatings. Look for models labeled ANSI Z87.1 with anti-fog treatment -
Apply Anti-Fog Wipes or Spray
Keep single-use wipes or anti-fog spray in your gear bag. It’s a quick fix, especially for older lenses without coating. -
Improve Ventilation
Choose glasses or goggles with indirect venting to allow airflow while keeping particles out. -
Fit Matters
Poor-fitting eyewear traps heat. Choose frames with adjustable nose bridges or foam gaskets for a better seal and less fog. -
Pair with a Proper Mask
If wearing a mask, ensure it fits tightly across the nose to avoid breath escaping upward.
