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. Here are a few strategies to help prevent your eyeglasses from fogging up.

Why Do Glasses Fog Up When Wearing a Mask?

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 — 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, wear a mask with a nose bridge or one that can be shaped to your face. When the mask fits properly, most of your breath will go through it, not out the top toward your eyewear.

Use Your Glasses To Seal the Top of Your Mask

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. This works best with large, thick frames.

Tape Your Mask to Your Face

Use easy-to-remove adhesive, medical, or athletic tape to secure your mask across the bridge of your nose and the top of your cheeks.

Soap and Water Help Prevent Fogging

This is a trick healthcare professionals regularly use. Simply rub both sides of your lenses with a drop of dish soap, then buff the lenses with a soft microfiber cloth. This creates a transparent, thin film that acts as a barrier against fogging.

Anti-Fog Wipes and Sprays

Anti-fog wipes and sprays are another effective option. Read the fine print carefully, as certain solutions may not work as well with some lens coatings.
