Why do glasses fog up in winter.
Fogging of glasses in winter is a common phenomenon, and the main reason for fogging of glasses in winter is the large temperature difference between indoor and outdoor. Indoors, the temperature of the glasses is higher than the surrounding air, and when you go outside, the water vapor in the air will condense on the surface of the glasses, forming a layer of "fog".
How to prevent your glasses from fogging up in winter.
a.Use anti-fog lenses: Anti-fog lenses have a special coating on the surface to prevent water vapor from condensing.
b.Use an anti-fog spray: An anti-fog spray can form a protective film on the surface of the lens to prevent water vapor from condensing.
c.Keep your glasses clean: If there is dust or other dirt on the surface of the lenses, it will be easier to attract water vapor condensation.
What should I do if my glasses have fogged up?
You can gently wipe the surface of the lenses with a clean cloth or use a professional eyeglass cleaner and cloth to clean the lenses.
