Why do My Glasses Fog Up?

Your glasses can fog up because of condensation. This occurs when warm air touches a cold surface, like your glasses lenses. This is why when you go from the cold outdoors into a warm room, you may notice that your glasses fog up.

This can also happen when you wear a face mask. As you breathe, most of the warm air escapes through the top of your mask onto the lenses of your glasses, which can cause them to fog up.

How do Anti-Fog Lenses Work?

Anti-fog lenses have a special coating which absorbs moisture from warm air on the lens. This prevents them from fogging up.

Whether you’re wearing a mask, stepping indoors during winter or enjoying a hot drink, anti-fog lenses keep your glasses clear, without you needing to stop, spray and wipe your lenses.
