  • STREAM 2 SEA Defog -and- OMID swim goggles are GREAT together
Style: 2 Fl Oz
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’. ... show more

  • Crystal-Clear Vision Underwater with Zero Fogging
Style: 2 Fl Oz
I recently used this mask defog while getting my dry suit certification, and it performed exceptionally well. The formula isn't as thick as other brands I've tried, making it easy to apply and more effective in keeping my mask fog-free. I experienced zero mask fog, which is quite unusual for me. An added bonus is that this defog solution is reef-friendly, which great to know that I can keep my mask clear without harming coral reefs. This defog offers the perfect balance of performance and environmental responsibility. Highly recommended! ... show more

  • Excellent defogger!
Style: 2 Fl Oz
This is the best defogger for swim goggles I have found. I swim laps nearly every day for over an hour each swim. It takes just one drop for both lenses. I use my finger to swirl the defogger around on all the inside surface of each lens, then put a small amount of water in each lens and swirl the water around. Because the lenses will be wet after this, it's best to prepare your goggles the night before so the water has time to evaporate. My goggles stay clear my entire swim. Highly recommend this product. ... show more

  • Worked exactly perfectly every time
Style: 2 fl oz (Spray)
This was super easy, compact, lasted through two weeks of snorkeling in the Galapagos, and never had my mask fog even one single time. We followed the instructions on the bottle. Everyone else on the boats on our snorkeling trips would ask us to use this because it worked better than whatever they were slinging on the boat. We reapplied one minute before each time we got back in the water. ... show more

  • Anti fog works well
Style: 2 fl oz (Spray)
I play pickleball and water Volleyball. I use the product on my glasses to help prevent them from fogging up during aport activities. I will also use it for snorkeling too.

  • Works but a little thick
Style: 2 Fl Oz
Maybe it's just me but I like really thin defogger that is easy to wash off with one dip in the water. This one is a little thicker than I'm use to and takes about 3 dips in the water to get it off. All-in-all, it works as advertised.

  • Prevents fog
Style: 2 Fl Oz
It prevented fog on my goggles for a half hour doing laps. Sometimes at the start I had to smooth out the layer of defogger but no big deal.

  • Clear and Crisp Sight
Style: 2 Fl Oz
I wear only non tinted goggles because my eye sight is poor. I feel more confident in the pool when my googles gives me clear vision and this product does that.
