How To Prevent “Mask Fog” on Your Glasses

Foggy-Glasses-Mask_650x350

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 specs fog up when the mask directs your warm breath upward instead of in front of you — which is great for preventing virus transmission but bad for anyone with less-than-stellar eyesight.

Is Your Mask Well Fitted? 

The mask should fit securely over your nose. Ideally, you'll want to wear a mask with a nose bridge or one that can be shaped or molded to your face. When the mask fits properly, hopefully most of your breath will go through it, not out 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 snug fit that blocks your warm breath from escaping upward toward your eyewear.

Tape Your Mask to Your Face

You can always 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. Just be  sure to stay away from 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. Stay away from soaps with lotions in them as they can leave a thick residue, making it even harder to see.

Simply rub both sides of your lenses 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.
