How to wear glasses and a face mask without getting them fogged up (image via post-gazette.com)

Wearing glasses with face masks are so stressful and the worst part of all the stress is, you have to deal with your glasses getting fogged up so…how do you avoid this???

When you’re wearing a face mask, you repeatedly breathe out warm air. This air then sneaks out the top of your mask and steams up the lenses of your glasses, making it difficult to see. The “misting” of lenses occurs when warm water vapour from your breath lands on the cooler lenses, producing tiny droplets that scatter light and reduce the lenses’ ability to transmit contrast (when light colours remain light and dark colours remain dark).

Now that we know the science behind this, how do we avoid getting fogged up glasses while going about our business in a face mask?

1. Wash the lenses with soapy water

The study from The Annals of The Royal College of Surgeons of England supplies a simple solution to the foggy-lens problem, which it refers to as an “annoying phenomenon.”

Authors of the study recommend that before slipping on a face mask, you should wash your glasses or sunglasses lenses with soapy water and shake off the excess moisture. Then, let your glasses air dry or gently dry the lenses with a clean microfiber cloth.

Cleaning the lenses with soapy water leaves a thin film that reduces the “inherent surface tension” and prods the water molecules to form a transparent layer. To avoid damage, don’t clean your lenses with products like baby shampoo, toothpaste or shaving cream.

2. Seal the mask

A common trick employed by doctors involves sticking a piece of double-sided tape across the bridge of the nose before putting on a mask. Experts in face mask products say “If you place the double-sided tape between the inside of the mask and the bridge of your nose, it will create a better seal,” “You can also place an additional piece of cellophane or masking tape over the mask as well.” 

…or, just use a band aid if that will work.

3. Make sure the mask fits well

A loose-fitting mask lets exhaled air, head toward your glasses, but a snugly fitting mask can shoot that air out of the bottom or sides of the mask and away from your glasses. For a better fit, get face masks equipped with moldable pieces around the nose (such as a metal strip) or masks that come in various sizes. If the mask is well-fitted, it will dramatically help to prevent the amount of hot air that can reach the lenses.

If you’ve crafted your own cloth mask, create a seal around the nose by inserting a moldable item into the upper part of the mask, This could be a paper clip, pipe cleaner, twist tie or folded piece of aluminium foil.

4. Adjust your glasses

Pushing your glasses forward on your nose will allow more air to circulate and keep your breath from fogging up your vision even though you just might end up looking like a nerd or old woman/man.

6. Wear your glasses over your mask

Always make sure the glasses rests on the face mask and not underneath it.
