With face masks (or face coverings) now compulsory in shops and supermarkets across the UK, the dreaded ‘glasses fog’ is something we’re certain all glasses wearers can relate to. But wearing glasses with a face mask doesn’t mean you have to suffer from fogged up lenses. In fact, there are a few simple tricks you can try to stop your glasses from fogging up when wearing a face mask. Let’s jump in.

Why does it happen?

When wearing a face mask, your airflow is expelled upwards out the top of the mask. Unfortunately for us glasses wearers, that airflow heads straight for our glasses lenses. 

When the warm air you exhale comes into contact with your glasses lenses, fogging occurs because your lenses are much cooler than the air you exhale. It’s really that simple, but it can be incredibly frustrating! Thankfully, it’s easy to prevent it from happening.

How to prevent your glasses from fogging up

Step 1: Adjust your face mask

A face mask that doesn’t fit properly is often the biggest cause of glasses fogging up. Your mask should be snug against your nose and cheeks, leaving little room for air to escape. To adjust the fit of your face mask, you’ll need to tighten the straps that loop around your ears. Most face masks come with adjustable straps but if not, you can try to loop them around your ears twice for a really snug fit.

Step 2: Adjust the nose fitting

Most face masks also come with adjustable nose fittings that can be bent into place. To stop your glasses from fogging up, make sure your nose fitting is tightly pinched around your nose. This will help to prevent the upwards airflow towards your glasses. You can even use your glasses to help secure the mask in place by placing them over the top of it.

Step 3: Breathe downwards

You can also help to prevent your specs from steaming up by breathing down into the mask. This will help to reduce the upwards airflow towards your glasses. It might feel a little weird at first, but once you’ve got used to it you’ll find it really does help.

Step 4: Adjust your glasses

Glasses that slide down your nose can also be a problem. The closer they are to the open edges of the mask, the greater the chance of them steaming up.

Thankfully, all of our prescription glasses and sunglasses can easily be adjusted at home to fit the shape of your face. There’s no need to take a trip to the opticians to get them adjusted, simply take a look at our guide on how to easily adjust your glasses and ensure a snug fit with minimal fog.
