Wearing a mask with glasses is not always very pleasant. Why? Because as soon as you breathe, fog forms on the lenses! You can no longer see anything and you have to wipe them constantly. This poses a safety problem when riding a bike. Some people put the mask under their nose but it loses all its effectiveness. Let's see how to avoid fogging on your glasses when cycling.
How does fog form on glasses?
When you exhale, the warm, humid air rises up along your nose and creates condensation when it comes into contact with the colder lenses. This is when fogging occurs. This phenomenon also occurs in winter when you move from a cold place to a warm place or in summer from outside to a very air-conditioned room. In both cases, it considerably blurs your vision and is even more dangerous when cycling.
The hospital technique of plaster
To reduce air leakage at the top of the mask, many healthcare professionals tape the top of the mask around the bridge of the nose.
Use liquid soap, dishwashing liquid or shaving foam
This technique is well known to divers. Apply the product to the lenses with your fingers and then wipe with a soft cloth or tissue. The fog appears and then disappears immediately! The soap actually leaves a thin film that prevents the fog from settling.
There are also anti-fog sprays in the trade.
A perfect seal with the face remains the best solution
The more the mask is in contact with the face and therefore airtight, the less air will rise up the nose. It will then come out through the wall of the mask, provided that the fabric is sufficiently breathable of course.
The presence of a flexible aluminum noseband sewn into the edge of the mask at the bridge of the nose allows the mask to be well sealed on each side of the nose, but this is generally not enough.
Adjusting the elastic to the correct tension also helps the mask fit better to the face, but many masks are not adjustable.
Why do Frogmask anti-pollution masks not fog up glasses?
Frogmask masks have been designed to guarantee an optimal seal and prevent fogging of glasses.
- The D mesh fabric used for the structure of the mask is ultra-breathable.
- Each mask has a flexible aluminum noseband at the nose.
- Each filter is also equipped with a noseband which ensures a double barrier at the most sensitive point for leaks. Exhaled air tends to rise up the nose.
- Their fastening system with velcro behind the neck can be readjusted at will, so the mask perfectly fits the shape of your face.
- 3 sizes (M, L and XL) allow you to choose the mask that best fit with your face shape. A one-size-fits-all mask does not allow this.
This is why you won't get fog when you breathe into a Frogmask face mask wearing glasses. If this is the case - some nose shapes and/or glasses may be incompatible with a mask - you will be refunded.
