Anti Fog Spray Eyeglass Lens Cleaner, Long Lasting Defogger For Glasses, Goggles, Ski Masks Mirrors and Windows

My personal experience with this product is fairly good. After reading the instructions, I sprayed the product on the interior of my swim goggles and buffed with a microfibre cloth as directed. Later the same day I put the goggles on and went swimming. After about 12 minutes of swimming the goggles started to fog, had to stop, rinse with pool water, drain cups and then proceed with my workout. I had to stop every couple minutes to clear the fog.The next time swimming, I sprayed the goggles with two spritzes each cup, swirled the liquid to assure full coverage, let the product dry, then again buff with a microfibre cloth. This time swimming, I had NO fogging at all for continuous 30 min swimming in 87 deg water.So my experience was to completely coat the surface, let dry, then buff with microfibre cloth.Hope this helps others.

Obviously a product like this can not claim to defy the laws of physics, but this spray does help a little. I use this in the humid and disgustingly hot state of Florida for my glasses and I have noticed a small difference in how much it fogs up when I use this spray. I primarily use it in the mornings for cleaning my glasses and it works great to clean them with a microfiber cloth. When using this spray, fogging still occurs, but it is much fainter and less often than without it. Sometimes now my glasses will fog up near the top and I won't even notice for a bit. Like I said, there is no way to defy the laws of physics, but this spray does certainly help fight the fog.

Don't listen to the one star review of this product. This product works wonders! But you have to know how to apply it!I started a new job where I work in a room and it's just steam everywhere. It was real difficult for me to see through the steam with my safety glasses and my prescription glasses over one another. If one didn't fog up, the other would fog up. I almost quit my job because of this.But this spray has been a major game changer. I can now see straight through the steam and everyone in the room!To apply it correctly, just spray this liquid on the front and back of your glasses and let it sit for 24 hours. After 24 hours, don't even use a micro cloth to clean it. Just put them on and go. You will see great results. The steam doesn't fog up my glasses any longer.

This is a good product in terms of how it keeps away from fogging ski/swim goggles. The very important trick is once you spray on dry lenses, you must let it dry (I just let it dry minimu an hour or let it dry over night for next day use) before using it. For water goggles, I just dip into the water before using it. It has been working very well if you follow this rule. If you don't wait drying process or wipe out too quick, then goggles will get foggy.

It's ok. I bought it to keep my glasses from fogging in the cold when I'm out shooting. I'm a photographer. It doesn't really work for my purpose. My glasses still got fogged. It must be more for swimming goggles.

Things I hate the most, when I open my dish washer and my glasses fog up. I hate it. I bought this anti -fogger to help prevent that and things like on rainy hot days when the humidity adds to my foggy problems.The spray comes in a bottle perfect size to fit in my purse and I was glad to see the bottle was nice and secure with no leaks. The bottle is easy to spray, and the spray goes on without being oily or leaving streaks on the glasses. The spray appear to work really well. The edges of my glasses still fog a little but for the most part this has been very helpful.

i bought it, tested it on some safety glasses the same kind i would need for work and for playing airsoft/paintball. the liquid spray went on clear i waited 5 min for it to set. put on my glasses and fog tested them under normal conditions they still fogged up. then i tried spraying them both sides wiping in, so on and so forth i tried 3 to 4 different application combinations with 3 separate pairs of lenses i could find. in each test to my disappointment they fogged.

This stuff simply doesn't work. I appreciate the comments saying "nothing will work all the time." But this stuff doesn't work any time. You'd be better off using the old potato juice trick — it works way better. I tried to return this but they won't pay shipping, so it wasn't even worth the hassle.Save your money.
