Why Do Your Glasses Fog Up When You Wear A Mask?  

The scientific explanation behind your glasses fogging when you wear a face mask is pretty simple. When you're breathing under your face mask, your warm breath passes through the top part of the mask and directly into your glasses. As a result, the moisture in your breath creates condensation on your lenses, and your glasses fog up instantly. You might have noticed the same thing happening when wearing your glasses with a headscarf during the winter season or when you walk into a warm place after being outside in the cold. Sometimes you can't prevent getting your glasses fogged up, but there are a few easy tips and tricks to do so when you wear a face mask.

How To Stop Your Glasses From Fogging Up When Wearing A Mask?

There's always a solution for everything, even fogged up glasses! Ophthalmologists and optometrists have found several helpful ways to stop your glasses from fogging up and prevent getting condensation on the lenses. Let's check them out:

 

✔ First and most important tip: make sure your mask is fitting properly. Most medical masks have a bendable and flexible metal strip to ensure the best fit around your nose and cheeks. It is not necessary to have a surgical mask for a good fit. If you're planning to make and use a homemade mask, you can sew in a pipe cleaner or a twist tie to the top of your mask. By doing so, you can always ensure the best possible fit when wearing your mask, just like the medical ones. You might also want to adjust the mask's straps or ear loops, as this can also help get a better fit. Once the mask fits well, your breath should pass through the mask anymore, and this will stop your glasses from fogging up.

 

✔ Most doctors around the world have been using tape around the top part of their mask to stop their glasses from getting foggy. You can also apply this tip and do it by yourself. You can tape the top part of your mask from cheek to cheek, through the bridge of your nose. When doing so, avoid using duct tape, as this may irritate your skin. Adhesive, athletic, or medical tapes would be ideal. Before using a specific kind of tape, make sure to test it on a different part of your body to ensure that it will not irritate your skin.

 

✔ Another simple way to get rid of fog on your glasses is to pull the mask higher on your face. To block the flow of air, use the weight of the lenses on top of your mask. Depending on the pattern and shape of your eyeglasses, this can be easy to do. In the case of large and thick frames, this method works perfectly!

 

✔ To protect your lenses from condensation, you can treat your lenses with an anti-fog spray or use an anti-fog wipe. These products are very effective in preventing fog on your lenses and can easily be purchased at your local optical shop or online. With the price varying from 10$ to 60$, some are pricier than others, so make sure to shop around and find a product that best suits your budget. Keep in mind that some anti-fog solutions might not work well with certain lens coatings, like anti-glare or anti-smudge, so make sure to read the instruction written on each product or to consult your optician before buying anything.

Should You Use Soap On Glasses to Prevent Condensation?  

You may have heard of several home remedies or DIY hacks to prevent your glasses from fogging up. Some of these include using soapy water, shampoo, toothpaste, or even shaving cream to prevent the glasses from fogging up. These methods are ideal for a temporary solution but are not as effective longterm. Using soapy water to clean your lenses and letting them dry will help prevent condensation from forming on them. This happens because the soapy water works as a surface-active agent, or as a surfactant, and leaves behind the thin film that helps prevent condensation. Although there is no real data about this, any substance that works as a surfactant on the surface of the lenses can be beneficial to help prevent condensation. Liquids like soap, baby shampoo, shaving cream, and toothpaste all work similarly. Keep in mind these hacks are only temporary solutions and will not be as effective as the professional anti-fog products sold on the market.

Types of Face Masks

Now that we've covered how to stop your glasses from fogging up when you wear a mask, it's equally important to know how you should wear a mask properly and what types can be used as an alternative. The most effective masks are certified N95 respirator masks or medical grade surgical masks. You can also use a hand-sewn one with an added filter inside as an alternative. However, these are not as effective since the fabric of a cloth mask may be porous and fail to provide a snug fit around the nose and the cheeks, therefore tiny droplets of bacteria can be still be inhaled. If you opt for a hand-sewn mask, it is essential to ensure a proper and snug fit around the nose, cheeks and jaw, as well as use an added filter inside to ensure optimal protection. You can find hand-sewn masks made with a designated pocket for a filter inside, so if you don't have access to an N95 or surgical mask, these can be a great alternative. With face masks in high-demand these days, you can easily find cloth masks hand-sewn professionally by different brands, designers and independent artists available on the market. The fun part about it is that they come in a variety of fashionable colours and stylish patterns for you to choose from!
