STREAM 2 SEA Antifog Spray for Swim Goggles, Snorkel, Dive Mask

Excellent. Wish I had found this 10 years ago!

Work well with swimming glasses. Though need to reapply before every session.

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!

Works brilliant. Expensive but a little goes a long way.

So I swapped from good old spit which had always worked well for me but is a bit gruesome, to this. The first dive I chickened out and also put spit in, my mask was so streaky I couldn't see much. Used this the next few dives and it was perfect. A drop on each lens, squidge it about, add a wee bit of water then leave sitting until you are ready to dive. Empty out the excess and put it on.

Does exactly what it says - stops my goggles steaming up during open water swims. I can actually see the marker bouys on the course now!

Works well. No problems.
