The problem is not new, as glasses always fog up when warm air meets cold: in other words, when you do sports and sweat, drink or prepare something warm, empty the dishwasher or get on the tram in winter. It usually only takes a few minutes for the water condensed on the lenses to disappear and your vision to be clear again. The situation is different when wearing mouth and nose protection, which is mandatory in public facilities and local transport as well as in all supermarkets due to the prevailing corona pandemic. Regardless of which respirator you wear, the lenses will always 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.
As you can already imagine, an anti-fog spray should ensure that you have a clear view – despite the respirator. This is made possible by first thoroughly cleaning your glasses or sunglasses and then applying the spray to both sides. And distribute evenly with a fine microfiber cloth. This forms a thin (transparent) film on the lenses, preventing water droplets from condensing on them. In plain language this means: your glasses no longer fog up. However, depending on the manufacturer, this condition only lasts for 24 to a maximum of 72 hours. You must then reapply the anti-fog spray for the glasses. Alternatively, there are also reusable anti-fog wipes that are intended to achieve a similar effect.
In addition to the anti-fog spray for glasses or sunglasses, there are other tips that can help prevent your glasses from fogging up so quickly:
