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 firstname.lastname@example.org 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.
They work as promised to prevent fogging, but the film isn't designed to stick to curved surfaces and/or plastic. I tried to install them on my safety glasses and they wouldn't sit flat so at least one edge was always detached. Where they were stuck down, they didn't fog, so that part worked really nice. When I came back several hours later they had detached from the lenses, so they either don't stick to curved lenses, or don't stick to plastic. I'm not sure which, but they won't work for my needs.
This product does not work as advertised at all.
I bought 2 sets expecting failure. And sure enough none of the 4 stuck to anything. Very disappointed but for the cost did not feel it needed to waste my time further complaining. But since I’ve been asked to review I would now say I dont recommend 2 stars for the concept. -2 for the application. They do t stick to anything glass or plastic lens. Tried both.
I don't know maybe I'm using it wrong but mine just didn't work couldn't see through it after I put it on the glass cuz I took both plastic sheets off of both sides is still can't see anything so I just do it in a trash
The protective film does not peel off sticky side easy. This causes fingerprints from touch ,then the vision is not clear. Not worth the money.
