How to prevent glasses from fogging up with a mask
Foggy glasses with a mask? Here’s what really works: sprays, correct folds, and recommended models.
Want to prevent glasses from fogging up with a mask?
Mask and glasses: a combination that often creates discomfort, especially in winter. Fogging is caused by breath rising towards the lenses. Let’s see how to prevent it with tested methods and useful accessories, without compromising vision or protection.
Why do glasses fog up with a mask
- The warm air from breath escapes from the top of the mask
- Condensation on the cold lenses → fogging
- The lower the outside temperature, the more evident the phenomenon
Practical solutions to prevent fogging
- Secure the top part of the mask well
Choose masks with a nose clip or add a foldable metal clip.
- Place the mask under the glasses
Create a barrier with the temples to direct the breath downwards. - Use anti-fog sprays for lenses
Available in spray or wipe form. To be applied every 24–48 hours.
- Bend a tissue inside the mask
Place it between skin and fabric to absorb moisture. - Prefer well-fitting surgical or FFP2 masks
Avoid loose or soft masks that let air through.
Errors to avoid
- Rubbing the lenses with rough fabrics
- Blowing on the lenses to "defog"
- Using soap or toothpaste (ruins treatments)
- Applying generic sprays not specific for glasses
Recommended brands and accessories
- Ray-Ban: lenses with optional anti-fog treatment
- Vogue Eyewear: ideal for lightweight masks, thanks to their low weight
- Tom Ford: well-balanced models with adjustable nose pads
- Anti-fog spray: professional to match (consult the optician)
