Few things are more frustrating than glasses that keep fogging up. Whether you’re stepping out of an air-conditioned room, wearing a mask, or cooking in the kitchen, foggy lenses can instantly blur your vision and slow you down. The good news? You’re not alone—and there are simple solutions to stop it. Let’s explore why glasses fog up and how you can keep your lenses clear.

Why Do Glasses Fog Up?

Fog forms when warm, moist air hits a cooler surface. For glasses wearers, this happens when:

• You move from a cold to a warm environment.

• You wear a mask and your breath escapes upward.

• You exercise, and sweat creates extra humidity.

• You cook, drink hot beverages, or open an oven door.

The moisture in the air condenses on your cooler lenses, creating that annoying foggy layer.

Common Situations That Cause Foggy Glasses

• Masks: One of the biggest culprits, especially during flu seasons.

• Weather: Shifting between outdoor heat and indoor air conditioning.

• Sports & Workouts: Running, cycling, or gym sessions increase humidity around your face.

• Kitchen & Hot Drinks: Steam and hot foods can fog lenses within seconds.

How to Stop Glasses from Fogging Up

Here are tried-and-true ways to keep your lenses clear:

1. Use Anti-Fog Lenses or Coatings

The most reliable solution is choosing lenses with a built-in anti-fog coating. At Mahdi Opticals, we offer specialized coatings that repel moisture and keep your lenses fog-free.

2. Anti-Fog Sprays and Wipes

Available at most optical shops, these products leave a thin protective layer on your lenses to prevent condensation. They’re quick, affordable, and effective for daily use.

3. Adjust Your Mask Fit

If you’re wearing a mask, make sure it fits snugly across the nose. Try masks with a wire bridge to seal the gap and direct your breath downward.

4. Wash Lenses with Soap and Water

Washing your glasses with mild soap (not harsh cleaners) and letting them air-dry creates a thin film that reduces fogging.

5. Choose the Right Frame Style

Frames that sit closer to your face can trap warm air, making fogging worse. Looser-fitting frames or those with better airflow may help.

What NOT to Do

• Don’t wipe foggy lenses with your shirt or tissue—this can scratch the surface.

• Avoid using harsh chemicals, which may damage coatings.

• Don’t ignore persistent fogging—it could mean you need a better lens option.
