Why Your Glasses Fog Up and How to Stop It

Glasses fog when warm, moisture-laden air contacts cooler lens surfaces and condensation forms. Anti-fog lens wipes disrupt the condensation process and provide hours of fog resistance. For mask-related fogging, conforming the nose wire tightly or using medical tape to seal the top gap resolves the issue.

Full video transcript

If your glasses fog every time you come inside from the cold, every time you open the oven, or every time you're wearing a mask — you're not alone. And there's actually a fix.

The fogging happens because warm, humid air hits your cooler lenses and condenses. Anti-fog coatings help, but most glasses don't come with them, and they wear off over time.

The fastest fix that actually works: anti-fog lens wipes. You rub one on each lens, let it dry for 30 seconds, and the fog stays away for hours. They're inexpensive and they work.

If fogging happens specifically with masks, the issue is warm air escaping from the top of the mask. Two fixes — bend the nose wire tighter against the bridge of your nose, or use medical tape to seal the top edge. Either one stops the airflow before it hits your lenses.

Small fix, big difference in your day.

Frequently asked questions

How to make your glasses anti-fog at home?

You can make your glasses anti-fog by using mild dish soap or some baby shampoo. Simply apply the soap or baby shampoo from your 'clean' fingertips, then rub gently on across both sides of your lenses. Rinse them under warm-ish water and make sure you're not using harsh paper towels to dry.

What can I put on my glasses to stop them from steaming up?

There are a number of anti-fog treatments and safe household solutions that'll do the trick.

How to get rid of cloudy haze on eyeglasses?

Make sure your hands are clean first, then wash the glasses using slightly lukewarm water before dropping a bit of lotion-free dish soap on the pair. Be super gentle about it as you scrub them, rinse completely, then dry them using a microfiber cloth.
