How To Prevent “Mask Fog” on Your Glasses

If you wear glasses and a face mask, you’ve probably struggled with “mask fog.”  Your lenses get all misty, requiring you to wipe your eyewear throughout the day. Below are a few strategies to help you prevent your eyeglasses from fogging up when wearing a mask.

But First, Why Do Glasses Fog Up?

Quite simply, condensation forms whenever moist warm air hits a cool surface. Your eyeglasses fog up when the face mask sends your warm breath upward instead of in front of you.  This is great to preventing virus transmission, but not so good for anyone that wears eyeglasses.

Is Your Mask Well Fitted?

The mask should fit securely over your nose. It is best to have a mask with a nose bridge or one that can be shaped or molded to your face. When the mask fits properly, most of your breath should go through the mask rather than through the top or sides.

Use Your Glasses To Seal the Top of Your Mask

This method works best with large, thick eyewear frames. By pulling your mask up higher on your nose and placing the lower part of your eyeglasses on the mask, you can get a more snug fit that blocks your warm breath from escaping upward toward your eyeglasses.

Tape Your Mask to Your Face

If this becomes more of a problem, you can use tape to secure your mask across the bridge of your nose and the top of your cheeks. Use easy-to-remove tape, including adhesive, medical, or athletic.  Don't use duct tape.

Soap and Water Help Prevent Fogging

This trick is one that healthcare professionals regularly turn to. All you need for this hack is soapy water (dish soap works best) and a microfiber cloth. Don't use soaps with lotions in them as they can leave a thick residue, making it even harder to see.

Simply rub the lenses of your frame with a drop of soap.  Then buff the lenses with a soft microfiber cloth.

This effective trick helps prevent your lenses from fogging up as a transparent, thin film of soap acts as a barrier.

Anti-Fog Wipes and Sprays

Another option is to purchase wipes and sprays designed to tackle foggy lenses. Read the fine print, as certain anti-fog solutions may not work as well, or may even damage lenses with  coatings that minimize glare and fingerprint smudges, for example.

This may be the right time to consider Contact Lenses or Orthokeratology.
