Cressi Premium anti-fog for diving goggles

Really recommend this! Easy to use, just one spray in each eye of the goggles and then rub in to let dry.Lasted the whole time I was swimming and then reapplied if needed for next swim. Good quality and effective at reducing fog/steam on goggles. Definitely worth the money!

Having ruined a fairly new pair of goggles by accidentally putting through a washing machine cycle, I decided to try an anti fog spray. There are so many mixed reviews out there, I have been hesitant to ever trial before.So the goggles misted up within about 10 seconds of use.I read countless reviews, all with different suggestions and felt bewildered.I tried various suggestions and each time I swam, goggles still fogged almost immediately.Then......I noticed a review which said they left the spray to dry then rinsed briefly and it worked.I was at the point of thinking the spray didn't work at all, so thought I would have one last try.I washed the goggles gently first and left to dry naturally. Only ever use a drop of mild baby shampoo for washing goggles.I then sprayed one spray in each lens, and contrary to what is usually said, never to touch lenses with fingers, smeared it gently to cover the entire lens. Left to dry. Rinsed briefly with clean water (actually used water from our de-humidifier as is more pure than tap water, also use in iron)Went to the sea, put goggs on dry and oh dear, fogged straight away. Anyway, I tried the other suggestion and swirled briefly in the sea and wow! I swam for 25 mins and still no sign of fogging!So I would say this spray is a game changer. I wished I hadn't thrown away my previous pair as might well have got them good again with the spray. I cannot comment how long the bottle will last, so only 3 stars for that, but will update after some while.I have managed to get 2 x 15..20 ,min swims from one spray, but generally find that I refresh each time I swim.I hope this helps to clarify a lot of mystery about this product! Happy clear swimming.I don't swim in chlorinated water so cannot comment how that would affect the spray. But it works in the sea.

Anti-Fog just isn't what it used to be anymore, however this product has managed to minimise some of the pain caused by misty goggles. I spray the anti fog before every swim and dip it once before putting the goggles on.The reason I do it every time, is that although it works. I don't think it stays effective over multiple swims. However I do clean my goggles regularly too as I swim both outdoors and in the pool, and want to keep the longevity of my goggles so I probably wash the coating off every time I wash them anyway. And because of requiring to do long distance outdoor swims, I can't run the risk of them fogging up after an hour and then needing to stop every 5 mins to wipe it away.Once you spray them, it looks like bubbles form, just wipe the solution around the goggles with your finger and leave to dry. Once dry, rinse once, do not put your finger back on the lenses as you run the risk of wiping off the anti fog coating. If like me you've accidently got it on the rubber eye part, just clean the solution off this area so your goggles still get a good seal.I have used this for long swims (12 hours) and once the solution is applied the anti fog does last the whole swim.

If you're an open water swimmer especially in colder waters then this stuff is magic. It prevents all my goggles from misting up and only needs applying every 4-5 swims. Lasts for a long time.

Disappointed as used 4 or 5 times in the pool and sea....my goggles are still fogging.I don't feel it was money well spent.

1) degrease mask lens (both sides) tooth paste and wash & dry2) spray lens liberally both sides & spread evenly with a clean cloth allow to dry, then rinse in fresh water before dive3) DO NOT over coat with any other offered pre dive treatment4) Post salt/fresh water dive rinse in tap water5) Lasts 4/6 dives - then use a lens cleaning spray as used to clean laptop/reading glasses lenses drying off before re- treating6) Repeat toothpaste routine after 2 cycles of respraying/ gap in divesTop Quality worth every penny !One treatment will last for 4/6 dives & a

I honestly don't know what these reviewers are on about I can only think they go in the pool to play with kids etc.I swim 50 lengths everyday and I'm yet to find googles that at some point don't Mist up ! (Still searching all advice welcome )This stuff stops a bit of misting but doesn't do any better than the coating on the googles , infact I would suggest you'll ruin your goggles smearing this around with your finger as I have just done .My advice is keep your googles dry inside from new inside as much as poss , don't touch the coating on the inside and rinse after with clean water , this gives me 30 or so Lenths until it starts to Mist .Putting this stuff inside for someone who does a lot of Leths will just give you sore eyes as it runs down the lense , total waste of money IMO , that's my thoughts anyway ! I feel like asking them to pay for the £70 googles they ruined ? But hey ho that's life !!
