How to Stop Your Safety Glasses From Fogging Up

Few things are more frustrating than raising your gun or leaning into a weld and finding your lenses fogged solid. Fogging happens when warm, humid air (from your breath or skin) hits a cooler lens and condenses. Here's how to actually stop it.

1. Choose glasses with venting

Airflow is your best friend. Frames with side and brow vents let warm air escape instead of pooling against the lens. Wraparound sport frames with channels move air as you move.

2. Use an anti-fog lens or coating

Anti-fog lenses are treated so condensation spreads into an invisible thin film instead of beading into a haze. Many Spits models ship with anti-fog polycarbonate lenses — the simplest fix of all.

3. Don't seal in your breath

Pull masks and neck gaiters away from your cheeks, or route your breath downward. Trapped breath is the #1 fogging culprit in cold weather.

4. Consider foam-padded frames — carefully

Foam-padded eyewear blocks wind and debris beautifully, but in humid heat it can trap warmth. Pair foam padding with venting and an anti-fog lens for the best of both. Browse our foam-padded safety glasses & goggles.

5. Keep lenses clean

Oils and dust give condensation something to cling to. Clean with a microfiber cloth; avoid paper towels, which scratch and strip anti-fog coatings.
