Every wearer of glasses knows the annoying problem: the moment you put on a respirator, the glasses fog up. Simply leaving out mouth and nose protection is currently just as out of the question as doing without a necessary visual aid. The only thing that helps is reaching into the bag of tricks.
The problem is not new, as glasses fog up when warm air meets cold: In other words, when you are doing sport and work up a sweat, drinking or preparing something warm, emptying the dishwasher or getting on the tram in winter. It usually only takes a few minutes for the condensed water on the glasses to disappear and for you to have a clear view again. The situation is different when wearing mouth and nose protection, which is mandatory in public facilities and in local transport as well as in all supermarkets due to the prevailing corona pandemic. Regardless of which respirator you wear, the glasses will permanently fog up. Unless you hold your breath – which of course wouldn’t be a realistic solution to the problem. Instead, you could use an anti-fog spray for glasses, for example. Read here what it is and how it works.

This is how an anti-fog spray for glasses works
As you can already guess, an anti-fog spray should ensure that you have a clear view despite the respirator. This is made possible by first cleaning your glasses or sunglasses thoroughly and then applying the spray to both sides. And spread evenly with a fine microfiber cloth. This creates a thin (transparent) film on the glasses so that no more water droplets can condense on them. In plain language this means: Your glasses will no longer fog up. However, depending on the manufacturer, this state only lasts for 24 to a maximum of 72 hours. You will then need to reapply the glasses anti-fog spray. Alternatively, there are also reusable ones Anti-fogging cloths that are supposed to achieve a similar effect.

These tips will help against fogged glasses
In addition to the anti-fog spray for glasses or sunglasses, there are other tips that can help prevent your glasses from fogging up as quickly:
- The closer the respirator is to the mouth and nose, the less warm air can get to the glasses – and fog them up. So always think about a secure fit when buying.
- When wearing a respirator (regardless of the model), always make sure that the frame of your glasses lies slightly on / over the face mask and not underneath it.
- First, place a tissue across the bridge of your nose before putting on a respirator. This way, the paper will trap the moist air from your breath and the glasses will fog up less.
- Secure the respirator to your nose with a wire or metal bracket, if one has not already been sewn in. This minimizes the gap through which the air you breathe rises to the glasses.
- Fold your top quarter of the respirator inward before putting it on. This allows more moisture to be trapped that would normally fog up your glasses.
- Clean your glasses with a little soap or washing-up liquid under lukewarm water and dry the glasses with a dry, clean tea towel. As a result, fewer water droplets should be able to stick to it.
