2 Pack of MistyClips (Black) Anti-Fog Mask Clip Prevents Glasses from Fogging and Steaming Up - Mist Free - Easier Breathing - Sustainably Made from Corn Starch

The recipient reports that they work well.

What more can I say except that it does not work on me. For me the design is all wrong - it fails to stop the moist air escaping in the gap between nose and cheek onto my glasses.

These clips work well for me and this is my second purchase.

Good servie from seller, thanks, but they make no difference or not a difference I can detect. Stil steam up badly. Feel a bit ripped off ... £8 for 2 useless bits of plastic?! Don't bother. :(

Wearing glasses and fogging up is a pain. I tried these clips. The first thing that is noticeable is the mask has to sit far lower on your nose (near the bottom, not at the bridge). This feels weird and takes a little bit of getting used to, but in the end becomes comfortable and not strange.There's an added bonus that when using the clip and the fogging restarts you know it's time to change the mask to a new mask. So the clip helps you monitor the lifespan of the mask it is attached to.

Such a simple idea but makes such a difference, minimising steaming up without impacting safety

Easy to fit and a simple solution. Immediate difference and stop spectacles steaming up when you wear mask.

Good idea but only one pair poor value for money
