STREAM 2 SEA Reef Safe Anti-Fog Spray for Swim Goggles, Snorkel, Scuba & Ski Masks – Defogger for Diving, Snorkeling – 2Fl Oz

Works great! Super easy to apply fog resistance is okay, enough to where you notice a difference but not super significant No visual appearance change and good size bottle for the price you pay

This spray is AWESOME!!! I got it to use on my regular prescription glasses because when i run on hot days, they fog up so badly I can't see anything. Conversely, if I don't wear my prescription glasses, I have a hard time seeing! The first time I used this spray, i didn't realize just how well it was working until I stopped for a drink of water and a couple of the runners in my group took off their glasses so they could see. That's when I realized my l3nses were perfectly clear! So, the best thing about this is you dont notice it working, but trust me, it IS! It's now a permanent part of my running gear.

Anti fog spray for swimming worked perfectly well I put it in, followed the instructions with finger in the lens. I let it dry and once it dried, no fogging up excellent product I would say I would suggest using it works

I was disappointed initially when my bottle would not spray. However, I received a fast replacement with my return and the second bottle sprayed fine. I tested it out in the bathtub and walking around the house. Yes I felt like a little kid playing with my toys in the tub. ha ha I could not get it to fog. I did this after doing a toothpaste scrub on my old mask to get old oils off. I tried my mask after the scrub without the antifog and it still fogged. The spray was the solution. I am traveling to snorkel soon and I fell pretty confident this product will perform well. I want to advice anyone with a brand new mask or a older well used mask to google how to do the scrub on your mask. the initial oil and the buildup of oils hold moisture that causes fogging.

This stuff works really well. Bought this because I had to remove the original anti-fogging material. Easy to use and works very well. Would buy again!

We have our own snorkel equipment and have it used for the last few years (we each have very different types of masks). I purchased this for our most recent snorkelcation in early April 2026. For my mask, the spray provided crisp visibility with zero fogging each day I had used it (3 days). On the fourth day, I did not use it and my mask had a little bit of fogging as a result, although fogging has never been a significant issue with my mask. For my husband's mask, the situation was different. The first day his mask had zero fogging, but he experienced significant fogging on the remaining 3 days. To be fair, I think his issue was more related to the overall mask/fit versus a problem with the spray. I highly recommend giving this spray a try! How to use: before going into the water, we sprayed a few times into each lens of the mask and rubbed it around. We then used bottled water to swish around in the lenses and rubbed to remove streaks. Then we discarded the liquid and used a towel to blot the excess water inside of the mask. We will use this spray for future trips!

I picked up the STREAM2SEA Anti-Fog Spray not for swim goggles, but for my motorcycle helmet visor since winter riding gives me a ton of fog buildup. The spray kind of works — it definitely reduces fog, but not as much as I hoped for riding in cold temps. My biggest gripe is the application process. The directions feel a bit complicated for something that should be quick and simple, especially when you’re trying to treat a helmet visor before heading out. I really wish the instructions were more straightforward. To be fair, I’m pretty sure this spray would work great for its intended use on swim goggles, and I do like that it’s safe for different types of lenses. It’s versatile, environmentally friendly, and has potential — just not the easiest option for motorcycle gear. Overall, it’s decent, but I’d love to see a more user-friendly application method.

Likes: keeps goggles fog free and nice and clear the time you put it on, and the time after, but the third time they start to fog and then after that the effect is completely gone. I HATE that the instructions say to put it on with your finger because I am already seeing my nice new goggles get small scratches from doing this. So it’s okay and it works, holding up in durability for a couple of swims, but I wish there was a small pad or something that came with it so the goggles didn’t scratch. For this reason, I probably wouldn’t buy it again because using the product exactly as directed is ruining my Arena brand goggles that I love. I know it’s not anything else because I keep my goggles in a case between uses and I only swim in a lap pool. The scratches are round/circular and exactly the shape of how I rub, I’m not rubbing hard and I’m not really even doing anything other than spreading it around on the inside exactly as the instructions direct. So for that reason, I don’t find the value being worth it.

Ottimo prodotto

Yo lo uso para tema airsoft y la verdad que va muy bien pero si sudas mucho es verdad que tienes que echarlo otra vez pero cumple bien su función que es que no se te empañan las gafas

Funktioniert super

This is absolutely brilliant! I love snorkelling and was fed up of my mask fogging within minutes of being underwater. A quick search on Amazon and I came across this, figured I’d give it a go. Spent a fortnight in Mexico and snorkelled every day, used this and zero fogging issues the entire time. Highly recommend!

Iyem worked well espcially when glasses worn with a mask
