These are extraordinary and unprecedented times in which we live.  One of the many consequences of the pandemic we have to deal with is wearing masks to protect ourselves and those around us.  The necessity of wearing a mask in public places presents new challenges for those of us who also need to wear corrective eyewear.  The main challenge being foggy glasses.  When you exhale your warm breath migrates upwards and out of the top of the mask.  When the warm air hits the colder lens, it cools down and forms condensation, or fogging.

 

Rest assured however, there are solutions to getting you "out of the fog".  The following are some of the methodology for preventing fogging while wearing a mask:

 

1) Soap and water - wash your glasses with a mild soap such as dish liquid soap.  Shake off any excess moisture and let the lenses air dry.  When dry, or even almost dry, clean your glasses with a microfibre cloth.  The rationale behind this working is that the soap leaves a thin film on the lenses that acts as a fog barrier.

 

2)  Use anti-fog products. Similarly there are anti-fog liquids or anti-fog lens cloths that act on the same principle.  Just take caution that they are safe to use in conjunction with coated prescription lenses.

 




3)  Close the gap.  Ideally your face mask should have a wire that extends around the nose area.  If you have this wire, make sure to pinch the top of the mask to fit the shape of your nose.  The idea is to minimize any possibility of air flow rising up and escaping the mask.  If the mask doesn't provide a close fit then an alternative is to use a medical or athletic tape along the top of the mask, thus acting like a seal.

 

4)  Pull up your mask. Adjust your mask to sit higher on your face, allowing your eyeglasses to rest on top of the mask.  This effectively blocks the airflow around your nose with the pressure of the frame holding the mask against your face.

 

5)  Placing a folded tissue over the bridge of your nose but under the top edge of the mask allows the warm air to be absorbed by the tissue rather than escaping upwards.

 

It may take some trial and error, but hopefully one or more of these tips will help to keep your glasses fog free while wearing your mask.
