1. Wash the glasses with soap and water

A study recommend that before putting on a face mask, wash your glasses or sunglasses with soapy water and gently shake them to remove excess water. Then allow them to air dry or gently pat dry with a clean microfiber cloth. This method, the study states, would prevent your glasses from fogging up when you put on your face mask. Why? Cleaning the lenses with soapy water leaves a thin film that reduces the “inherent surface tension” and pushes on the molecules, which form a transparent layer. 

  1. Seal the mask

A common trick used by doctors is to stick a piece of double-sided tape over the bridge of the nose before putting on the mask. If you put the double-sided tape between the inside of the mouthpiece and the bridge of your nose, you will get a better seal. An additional piece of cellophane can also be placed over the face mask.

  1. Make sure the mouthpiece fits properly

A loose face mask allows exhaled air to direct your glasses. One that fits properly can send that air out, through the bottom or sides of the mouthpiece, away from your glasses. For a better fit, opt for mouthguards with moldable pieces around the nose (such as a metal strip) or those that come in different sizes. If the mask is on properly, it will go a long way in preventing warm air from reaching the glass. Make sure you get a good fit over the bridge of your nose. The closer the mouthpiece fits to the bridge of your nose, the less warm air your glasses will reach. If you made your own mask out of fabric, add a form of sealing around the nose by inserting a moldable element into the top of the mask. You can use a paper clip, a pipe cleaner, or a piece of folded aluminum foil.

Very important: Always make sure you discuss and make decisions about your eye care based upon a formal appointment with your optician.
