I've used Speedo anti-fog spray for years, but Spit does a better job keeping my goggles from fogging. I found that my eyes slightly burned when I applied and rinsed Spit on my goggles right before swimming. I started treating my goggles with Spit after I swam and the next day, my eyes didn't burn.

Kept swim goggles from fogging for 20 laps but on the bottle it says not recommended for swim goggles. Do not remember reading that on the website description. It does cause eye irritation so be very careful when rinsing SPIT out of goggles and do not leave any water in them as it gets in your eyes and irritates them like crazy!

I will never buy Speedo again!  This is far far better than Speedo.  Totally recommended.  Next time, I would like to try the spray.

Works great.  Haven't had a problem with fogging since I applied it to my goggles.  The contents of the bottle I received seemed thicker than I expected.  It's more of a gel consistency, so I just applied the small dot, added some water and rubbed it in my goggles - rinsed and let sit overnight.  Didn't have any fogging, so I highly recommend it.

Does seem to control the fog, but it burned my eyes so much the first swim, I had to stop my workout. Not sure I'll use it again.

This stuff is great!  Just put on drop in each eye of the goggle, spread it around, rinse it and voila, you are ready to go for a fog-free swim session.  I typically only swim 30 minutes at a time and this stuff works wonders!
