As the world adapts to wearing face masks to prevent the spread of COVID-19, many people are experiencing a common problem: foggy glasses. This issue is not new, as skiers and surgeons have long dealt with it.
When you exhale, the warm and moist air can cause your glasses to fog up. To prevent this, you need to block the air from reaching the lenses. Here are a few simple ways to do so:
Adjust Your Mask
One way to decrease the amount of fog is to pull your mask higher on your face. This allows the weight of your breath to be directed away from your glasses. However, this method works best with large and thick frames.
Use Soap and Water
Washing your glasses in soapy water and letting them air dry can help prevent fogging. According to an article in the Annals of the Royal College of Surgeons of England, the soap leaves behind a film that reduces surface tension and prevents fogging.
Insert a Tissue
Another easy hack is to place a folded tissue between your mouth and the mask. This absorbs the warm and moist air, preventing it from reaching your glasses. You can also ensure that the top of your mask is tight and the bottom is looser to direct your exhaled breath away from your spectacles.
Consider Anti-Fog Solutions
Commercial anti-fog wipes and sprays can be effective, but they can be expensive. Be sure to read the fine print before purchasing any anti-fog solution, as some may not work well on glasses with certain coatings.
