| Fogging while breathing with mask |
Wearing a mask is now mandatory in certain everyday situations to limit the transmission of the Sars-CoV-2 coronavirus. But goggles are not really compatible with prescription glasses, which can fog up, reducing visibility. Here are some tips to avoid this annoying phenomenon. Wearing the mask directs the hot exhaled air upwards, causing condensation on the cooler surface of the lenses, which will cause the appearance of fogging.
USE A PAPER TISSUE
In order not to be bothered by these tiny droplets "which scatter light and reduce the ability of glass to transmit contrast", it is specified in an article published in the Annals of the Royal College of Surgeons of England, one can in particular use a tissue. After folding the handkerchief horizontally, place it between the face and the top of the mask, so that it rests on the bridge of the nose. The moisture rejected by breathing, which is water in gaseous form, will then be absorbed by the handkerchief.
ADJUST YOUR MASK WELL

Wearing a properly fitted mask will also prevent hot exhaled air from reaching the lenses of your glasses. This is why it is recommended to use a mask reinforced with a thread that will model itself around the nose. For homemade masks, for example, you can use a piece of copper or wire.
WASH YOUR GLASSES WITH SOAP
Another solution is to wash the glasses in soapy water. Indeed, the soap will create a thin film which will prevent, in the short term, the mist from forming on the glasses. Just apply a small amount of liquid soap (such as shower gel or dishwashing liquid) to your glasses, then gently spread it on both sides with a microfiber cloth. Wait a few minutes, then remove the excess with another soft cloth to avoid scratching the glasses.
ANTI-FOG SPRAY

Note that this technique also works with shaving foam, which must then be rinsed off with hot water. Finally, there are sprays, also available in gel form, preventing fogging, which can be obtained from most opticians, which reopened on Monday, May 11. Same principle, just apply the product to your glasses and gently clean the lenses with a cloth.
