Everyone who wears glasses knows the annoying problem: As soon as it’s autumn, the glasses fog up every time you change location due to the temperature difference. However, foregoing the necessary visual aid is out of the question. The only solution is to dig into your bag of tricks.

The problem is not new, as glasses fog up whenever warm air meets cold air: i.e. when you do sports and sweat, drink or prepare something warm, unload the dishwasher or get on the tram or bus in winter . As a rule, the condensed water on the lenses disappears after a short time and you have a clear view again. However, if you don’t want to wait that long, you can use an anti-fog spray for your glasses. Read here what it is and how it works.

This is how an anti-fog spray for glasses works

Foggy glasses caused by breathing mask

In addition to the anti-fog spray for glasses, there are other tips to help prevent your glasses from fogging up as quickly when wearing a respirator:

  1. The tighter the respiratory mask fits over the mouth and nose, the less warm air penetrates the glasses lenses – and fogs them up. So when buying, always think about a tight fit.
  2. When wearing a respirator mask (no matter what model it is), always make sure that the frame of your glasses lies slightly above/above the mouth and nose protection and not below it.
  3. First place a tissue across the bridge of your nose before putting on a respirator. This means the paper traps the moist air from your breath and the glasses fog up less.
  4. 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 your breathing air rises to the lenses of your glasses.
  5. Fold the top quarter of the respirator mask inwards before putting it on. This helps trap more moisture that would normally fog up your glasses.
  6. Clean your glasses with a little soap or detergent under lukewarm water and dry the glasses with a dry, clean tea towel. This means fewer water droplets can stick to it.
