STREAM 2 SEA Mask Defog, Reef Friendly Defogger Coating Anti Fog Mask for Glasses, Snorkel Mask, Scuba Divers, Ski Goggles and Sports Glasses Equipment

Worked perfectly as it should have on recent trip to USVI. Excellent to have on hand, saves time, and the visibility was amazingly clear- no fogging at all. It is also environmentally friendly for coral reef and the ocean.

This stuff makes your goggles crystal clear. Easy to apply and easy instructions. It lasts a couple hours I would say, as we do have to reapply daily to all of our kids' goggles to keep them from fogging up. Before we started using this stuff, our goggles would fog up every two mins, so once a day is better than every couple mins. I'm sure it would last longer if my kids weren't constantly taking their goggles off and on in the water. Overall we are very happy with this purchase and I would recommend!

I bought this antifog spray for my goggles and I’ve been pretty happy with it. It definitely works, especially when I take the time to clean out my goggles and dry them off before applying. That step makes a big difference. The first time I used it, I didn’t do that and the results weren’t as good.I did have to reapply it after a few swims, but that might be because I got water inside my goggles while swimming. Even then, it still helped more than not using anything at all. When I use it the right way, my goggles stay clear and fog-free a lot longer.If you’re tired of foggy lenses while swimming, I’d say this is worth trying. Just make sure your goggles are clean and dry first, and don’t be afraid to reapply if needed.

I hadn't been diving in a while but am a highly trained one (Dive Master, assistant instructor, Rescue Diver). When recently getting my now 3 older children open water certified, I tried this reef safe product for the first time instead of some of the other usual go-tos. Wow! This stuff ROCKS! Absolutely ZERO fogging of all of our masks over the 2 days of diving in the ocean. None! I'm sold out on this stuff. Amazing product!

Excellent product. Keeps my swim goggles fog free for my entire 1/2 mile swims. Only one application necessary per swim. Definately will order again, highly recommend trying it out.

Didn’t help my issue with sport glasses fogging

On July 1, 2022 I purchased “2 oz. STREAM-2-SEA reef friendly Mask & Googles Defogger”,,, along with a pair of “OMID Comfortable Polarized Anti-Fog Swimming Goggles” (smoke, all black frame). I swim open water (quarry lake) 3-5 x’s per week during the warmer months, swimming non-stop for 60 to 120 minutes. I’d been using “Vanquisher 2.0” goggles the past several years but, despite correct adjustment, they would always begin digging into my eye sockets after an hour or so, and left me with a bad case of ‘raccoon eyes’. I decided to try out the OMID goggles, seeking greater comfort.The OMID goggles feature softer, larger eye cushions that are dramatically more comfortable. They truly do provide greatly-improved panoramic vision. The inner surface of the contoured plastic lenses have their own anti-fog coating, but such “factory coatings” are notoriously fragile and soon lose their effectiveness. I bought the 2 oz. Stream-2-Sea to help assure that the OMID goggles could remain fog-free as long as possible.Out of the box, I first gently washed the new OMID goggles with a minimal amount of Johnson’s Baby Shampoo (BS), --not their newer “Head to Toe” formulation. They are similar, but not the same. SEE MY PHOTO’s showing the slight differences in their published ingredients.A Word of Caution: When washing plastic-lens swim goggles, you always need to be as GENTLE as possible. A little particle of sand being rubbed across the lenses can scratch the heck out of them, permanently.OK,,, I rinsed my new pair in room-temperature tap water, then applied the smallest amount of BS, and used the slightest finger pressure possible, then rinsed them in the tap water. My tap water leaves ‘spots’ when it dries, so I do a final rinse with some distilled water for a spot-free finish.Once dry, I applied one drop of the Stream-2-Sea anti-fog gel to each inner lens and used my wet finger to GENTLY spread a thin, uniform coating. I then added a tiny amount of distilled water to each lens “cup” and swirled it a few seconds before pouring off the water. I allowed them to air-dry to a clear, streak-free coating, and then put them into my ‘swim bag’, ready for use. I swam 90 minutes in the 83F lake water that next morning. The goggles never leaked, and they never fogged up. The polarized, fog-free view was so much better than before.I finished my swim and I immediately put them into the OMID carry bag that came with the goggles, being careful to not touch the lenses (there’s no clean rinse water available at the lake). Once home, I washed my hands to remove any possible sand particles (which can scratch the plastic lenses) before rinsing the goggles thoroughly under tap water. Then I dabbed a tiny amount of BS onto each wet lens and used a modified* Q-tip to gently clean their fragile inner surfaces. (* I get a Q-tip and pull the cotton to stretch it longer, then use the stretched portion to gently go over the lens surface.)I then rinse the goggles with tap water, followed by a distilled water rinse. Before they dry, I use the Q-tip (or a tiny, soft-bristle artist brush) to paint a uniform coating of the Stream-2-Sea anti-fog gel onto the inner lenses. To smooth out this coating, I add some drops of distilled water to make a little ‘puddle’ in each lens cup. After a few seconds of swirling, I pour off the water and check to see that there are no remaining streaks of the Stream-2-Sea. If there are some streaks, I just rinse them with a few more drops of the distilled water and check them again. Once they are totally streak-free, I ‘stand up’ the goggles to let them air dry (similar to what you do with a washed dinner plate).I’ve now used my new OMID goggles 9 times, and they are still in like-new condition. Not a single scratch, and they never, ever fog. Over the past couple weeks, my swims have included few that were two hours long(in sunny, 90 degree Heat Wave conditions). My old “Vanquisher” goggles would begin fogging up in just a fraction of that time. The Stream-2-Sea anti-fog gel, in combination with the ‘factory’ anti-fog coating on the OMID goggles, has worked perfectly for me. And, the ‘soft-cushion’ design of the OMID googles has completely eliminated the eye-socket discomfort,,, and no more “raccoon eyes”.My goggle-washing procedure may seem very lengthy and tedious when you sit there and read about it, but it soon becomes routine, taking only 5 minutes. I can now enjoy swimming comfortably for HOURS with absolutely no fogging, and it’s keeping my $26 swim goggles looking brand new. The OMID comfort goggles -and- the STREAM2SEA anti-fog gel are an effective combination for any ‘distance swimmer’.

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.
