Jaws Quick Spit Anti-Fog Spray for Swim Goggles, Eye Glasses, Snorkel Mask, Scuba Divers, and Safety Eyewear, Made in The USA

This review is in relation to using this product on sports sunglasses (rather than swimming diving goggles). I play tennis and often on very sunny / bright days I wear sunglasses. The problem is that the inside of the sunglasses can steam up with the sweat/heat from your face. Hence the search for a anti-fog product.Does this work? Yes, in that it stopped inside of my sunglasses getting steamed up.The only issue I have with this is the instructions. It says spray on the lens, then lightly rinse off (presumably with water, though it doesn't say this). Problem when you follow these instructions is that it leaves smears across the sunglasses lens which impede your vision. Therefore, I sprayed again but this time lightly buffed with a cotton cloth instead of rinsing before allowing it to dry. That's how other anti-fog products I've used suggest applying it. Still seems to work but this time without the smearing.

This is ok, you must use the instructions or you will regret using it. When I did re read the instructions it worked correctly but isn’t the best I’ve used. I bought it to help keep my glasses clear from fogging when I have a mask on and I can’t say they did a good job.

You spray this on your lenses then rinse off, and do not wipe. It's quite annoying to wait for your lenses to dry completely. Having said that, it does make a difference. I don't always bother to use it because of the time taken, but worth a try.

Tried this swimming in the beautiful waters around the Greek islands. It keeps the mask clear. It does what is should do. I recommend it (although I've no experience of other brands to compare).

It does work but I have found you have to apply quite thick to be effective which means you have a smeary view through your lens. I use it on glasses under goggles when out motorcycle dirt riding for approximately 3 hrs and it does start to become ineffective within this time but will say I do get pretty hot and sweaty so would say it may perform better under less rigorous circumstances.

This is an amazing product for Paintball Goggles. There is no fog at all when using this spit spray. I'm a big guy so i sweat when playing paintball but yet still no midst. changes your game entirely. Bottle could be bigger though that's why i only gave it 4 stars

Works fine on my glasses. Barely works on my spiderman mask (plastic), which was the primary reason for buying. Avoid if using for plastic lenses

Had two sets of swimming goggles that steamed up after on half a length so was in desperate need of something that worked - after reading around, so glad I brought this! Applied one squirt into each goggle-eye smeared around and waited a minute or so before rinsing and left to dry overnight naturally. Did a full 45 minute swim the next morning and didn't steam up once. Amazing product! Very happy and easy to use :)
