This happens mostly when a person walks from a cold street into a house, office, store, or any room. Ways and tips to make sure that glasses do not sweat in the cold, we have collected in the material.

Fogging of glasses in winter – why does it happen?

The answer to the question of why glasses fog up in winter has a simple physical explanation. Due to the temperature difference between the outdoors and the warm room, when a person goes there, there is a cooling of the moist air on the cooled lenses of glasses. As a result, condensation from the air forms and settles on them. In some cases in frosty weather glasses may fog up for no reason, even if the person has not entered a warm room: in frost, the glass cools down and the warm air exhaled by the person settles on it. In heavy fog, when there is a high index of moisture in the air, condensation can also settle on the lenses just outside.
