Fog Stopper Anti-Fog Drops Treatment - Effective On All Lenses (AR Coated Included) and Screens - Prevents Fogging on Eyeglasses, Goggles, PPE and More - Stay Fog Free for Days - Made in USA

Used this in my airsoft goggles and shooting glasses. I add some before the match and after each match. It keeps the fog away for the majority of a round (30 min) but must be reapplied. I ended up selling out a bit extra for an ex-fog unit. Now that is definitely worth looking at. This solution is a great option for the meantime. Great value, fits in glasses case, great quality (better than rainx!!), easy to apply, no eye discomfort, versatile.

I am a photographer, and I shoot High School sports for the local newspaper. When sports finally started up again in the High Schools after being shut down for over a year, I started shooting football games. Due to protocols, I had to wear a mask while I was shooting. I found that every time that I exhaled, the warm air came out of the top of my mask, and fogged up my viewfinder. Needles to say I tried different things to try to stop the fogging. I tried tape on the top of my mask, and that didn't work. I tried using my saliva, but that was kind of gross....then I found Fog Stopper, and I no longer have fogging issues. I keep the bottle in my camera bag in case of emergencies. It is very easy to apply, and worked several times before I had to reapply.

This works fairly well in most situations however when wearing mask in very cold fogging occurs. Be sure to use per instruction otherwise it does not work.

I was hoping this product would work really well, but it did not perform any better than other products that I have tried. It performed no better for me than home remedies such as Dawn dishwashing liquid mixed 50/50 with hydrogen peroxide. I have new AR lenses in my glasses and was looking for something that was safe for them. This product is probably safer for AR lenses than dawn/peroxide, but did not perform any better as far as limiting fog. I prepped my glasses lenses and binoculars with disposable Zeiss lens pads and after they were dry applied "No Fog" per manufacturer's instructions. I still had significant fogging issues as did my brother. The product is pretty pricey so be aware that it may not work as well for you as you would hope. Additional: I have used this product on multiple occasions over the past week. Today the temp is 37 F and the relative humidity is 69 percent. I applied the product twice within 5 minutes on freshly cleaned glass lenses. I am not wearing a mask. The lenses fogged immediately after application. Spit, Dawn and the oil from the side of my nose works much better. Product is worthless. Save your money and clean your glasses with plain water and you will be just as satisfied.

I bought to use as an anti-fog for my eyeglasses while I wear a mask. It does work as an anti-fog but you do have to reapply as needed and each time you clean your glasses with water or cleaner. I would estimate that it works for about 3 to 4 hours if you are not breathing heavily under your mask. Follow the instructions on the box or bottle and once applied you can test your lenses by breathing on them. If you see a little fog then just go over that area again and you are ready to go fog free for several hours. Please keep in mind that temperature and humidity will have an affect on hours fog free. Overall, I would say it is better than nothing and I don’t think there are products on the market that are much better.

My eye dr recommended this for preventing fogging while wearing masks. I’ve relied too heavily on my contacts simply because I couldn’t wear my glasses with a mask. It works, mostly. For a few of my pairs of glasses it does great, but for a few it doesn’t work at all!? I’ve noticed that lenses that have an anti glare coating it has not worked for me at all.

Took my glasses on a hike and they didn't fog up

Hope this saves you some money. It is hands down the best on the market. Don’t bother getting the wipes or other sprays. They don’t work as well as this product. That being said, it prevents the fog but a layer of moister forms on your glasses. By it’s self it kinda works but if your active ie play airsoft you will need to another air blowing system to keep your vision.

Did not work

This is the second bottle I’ve bought. Works extremely well when using it for wearing a mask. Glasses didn’t fog up at all. It minimized the fog in winter but at -30 my glasses still fogged up a little. Not what they used to so I will definitely be using this again. I tried other anti fog products but they didn’t work nearly as well. I would recommend using this.

Not great. Works for about half an hour then you have to reapply.

J’ai suivi les indications du fabricant. J’ai utilisé le produit pour des lunettes de prescription. Ça fonctionne, sauf qu’on doit laisser un film de ce liquide sur la lunette pour que ce soit efficace. En laissant un léger film, il se crée des reflets dans la lunette, ce qui est un résultat non satisfaisant pour moi. J’aime que mes verres soient toujours bien nettoyés. Donc, Je ne recommande pas ce produit.

4 stars because nothing is perfect. The best I have ever used in a tough situation. Use it with glasses wearing a goalie mask while playing hockey. I get extremely hot and this mostly works. A satisfied customer.
