There is nothing more frustrating than pushing through a intense workout, hitting a massive hill, and suddenly having your vision completely blanked out by a wall of fog.
Foggy lenses aren't just annoying; they are a safety hazard. Fortunately, stopping the steam is relatively simple once you know why it happens.
Why Do Sports Glasses Fog?
Fog is just condensation. When your hot, sweaty face meets the cooler air on the outside of your lenses, moisture traps itself on the surface. To stop it, you either need to change the airflow or treat the lens.
4 Quick Ways to Clear the Air
-
1. Pull Them Down Your Nose: The closest your glasses are to your face, the more hot air gets trapped behind them. Simply sliding your frames a few millimeters down your nose bridge allows trapped heat to escape upwards.
-
2. Use an Anti-Fog Spray or Wipe: These products apply a microscopic, hydrophobic coating to the lens. Instead of bunching up into tiny, vision-blocking water droplets, the moisture flattens out into an invisible layer.
-
3. Look for Vented Frames: Next time you buy eyewear, look for models with built-in vents along the top or sides of the frame. These cutouts act like a chimney, pulling cool air in and pushing hot air out.

4. Keep Clean: Dirt, smudges, and facial oils give moisture something to cling to. A clean lens fogs up much slower than a dirty one.
