Excellent defogger
Excellent product. Found that it worked well when applied for around 5 mins prior to the dive. Swill with fresh water and it kept the mask fog free for the next two dives.

works well
Works well, I used this in Kos with my mask when snorkelling in the sea and it worked a charm! Easy to use, prevents fogging effectively, good value for money and definitely worth packing if your heading either snorkelling or diving 🤿.

Excellent value for money!
Only a tiny amount is required and then rinse well. I didn’t do that the first time and caused an eye infection, but tried again and was impressed. A little goes a long way and it’s really effective. I’ve not experienced any fogging of my goggles either in an indoor or outdoor swim over 2.5-4k distance. Value for money is excellent as so little is required!

Funktioniert super, wenn man sich an die Anleitung hält. Muss nach paar Tagen wieder neu aufgetragen werden, was aber absolut nicht schlimm ist.

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’.
