Review: STREAM 2 SEA Defog -and- OMID swim goggles are GREAT together - 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’.
Review: This defogger is amazing! - I have been snorkeling (and some diving) for nearly 50 years, and have always had trouble with my mask fogging. It was irritating and frustrating as i cycled through many varieties of defogger. Stream2 Sea Reef Safe Defogger,is the first and only product that has worked for me. It is good to know that the company developed a reef safe formula. Kudos to them for that. I just returned from a snorkeling vacation, and the results were wonderful. NO fog at all. I highly recommend this product. Follow the instructions and use just a tiny bit. I hope that you will be as pleased with it as I was. Happy snorkeling!

## Questions & Answers

**Q: is this safe for anti-glare coated glasses**
A: It should be fine. I’m an optometrist and have been using this on my glasses that have the AR coating. I’ve also been using this on the oculars of my slit lamp (microscope to examine eyes) and 78D condensing lens (magnifying lens to look inside the eyes). So far no problems and it’s been working great.

**Q: Do I dry my eye glasses after application?**
A: I’ve been rubbing in the solution with a lens cloth until it is clear/streak-free.

**Q: Does it work on gas mask?**
A: it should work on any glass prone to fogging

**Q: Does it work on Football helmet visor?**
A: Sorry  I have no idea. In theory it should work but never tried

### ⭐⭐⭐⭐⭐ This defogger is amazing!

### ⭐⭐⭐⭐ Works well for at least two swims at a time but using as directed does scratch the goggles.
*by A***E on September 6, 2024*

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.
