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 use this product on a daily bases for keeping a plastic face mask spit free. The product does not work if you wipe off immediately. I smear on a drop and then wait 30 sec to a minute before wiping with a paper towel or cloth. I have bought this product twice and I am happy with the brand.Pros: prevents moisture build up, only requires a dropCons: very small amount of liquid for the $$$$

The first application did not go well, but it could have been I did not apply it correctly. Finally got the glasses to not fog, but did not last the whole nine hours of work. Again, it could be something I am not doing correctly, or something else going that I am unaware of at this time. However, the glasses did not fog up for six hours. I was happy with that part.

This product does help and slow down fogging of the glasses but every since putting it on my glasses I CAN NOT get rid of the haze on my glasses..

I used it on my safety glasses at work. Does not work in the slightest. I even tried to put on another coat of it after and it still didn’t work. Don’t buy it. It’s a scam

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.

No fog when you apply to both sides of each lens. I was skeptical but going on 3rd bottle now.

Best stuff I've ever used

Did not work

Works very well! Use it on my bike helmet shield to stop it from fogging up while riding to/from work.

This one really works! I put a few drops on each eye befor playing sports and what used to be a super foggy experience turned out to be quite nice!

Make sure your glasses are clean and dry before applying .I'd suggest wearing a mask and gloves while applying this substance, the chemicals seem to off-gas into the surrounding environment until it sets/dries. I personally prefer, while using gloves, to use a finger to spread the solution across the lens with light pressure until it starts gelling up and becoming tacky. Then, I'll use a clean microfiber cloth to spread the coating around in swirls so it's even. Then, I'll use a hairdryer to blast it with warm air to set it quicker. If your hairdryer only has a hot setting then do it from further away so as to not warp the lens.The result is quite impressive where breathing on the lens would not create any fogging.However, after waiting a few days to make sure it set completely, I rinsed one lens under low pressure cold water (no soap or cleaning solvents), and the coating completely disappeared. I think it either dissolves with water or doesn't adhere particularly well to my lenses. I'm a person that normally cleans my glasses with dish soap and water so this coating isn't for me, but it might work for those that clean using a micro fiber. I haven't tried that yet.

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.
