Fog-X for Glasses

  • Fits any eye wear
  • 1.5x1in (4x2.7cm) oval
  • Lasting anti-fog and scratch resistant
  • Easily peeled off without residue leftover  

Born out of the COVID pandemic, these larger versions of Fog-X are meant to be used in regular glasses which fogged up when healthcare workers wore masks. 



Are the inserts blue or clear?

Clear. There are protective films on both sides of the inserts that need to be removed with the pull tabs. One of these films is blue, but should be off by the time you are ready, leaving a clear insert.

Does the insert fit any glasses?

Mostly yes. Some glasses are a little small and you may need to cut down the edges of the Fog-X insert using scissors. For most glasses, there is no issue.

Do the inserts work on very curved glasses, sunglasses or protective lab eyewear?

If the glasses are very curved, the inserts won't work because the adhesive is not strong enough to handle the curvature. You can however cut the inserts hamburger style and place the side by side as pictured below. We are working on making these a stand alone product too.

How long does the anti-fog effect last?

Over a year! 

My glasses are still fogging up bad on the first use or the insert won't stick on the glasses...

Sometimes, an extra layer of protective films is left on the insert. This keeps the anti-fog or adhesive layer covered up so it won't work. You can try to pry off this extra layer or use a piece of tape to peel it off. If all else fails, just hit us up at for a new pack!

They worked for a few days but are now fogging up... 

The inserts can get dirty quickly. Just rub them real well with a tissue or T-shirt and they should clear up right away. Fog-X is very scratch resistant and you won't harm it by rubbing.


Can I peel it off and replace it?

Sure. You won't need to, but you could. The adhesive is silicone based and leaves no residue on your goggles. If you need to replace them, simply peel them off and stick new ones in.

Doesn't work for me

They don't fog up with tiny droplets but they make my vision swimmy and I still can't see

Lasted about 2 weeks

1. I only bought 1 pair so the outside of my glasses still fogged up. Didn't realize I would need on both sides of lenses.
2. I could never get a big bubble out. It kept coming back. Super annoying.
3. I finally try to reposition and then lost the lens.
Not worth it. Didn't really work.

Installed the Fog X only to realize that the blue tint ruined my vision.

Hello Pete. You need to remove the blue protective film! The anti-fog insert is clear once you remove the film. Check out our video for more details.
