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

I have used other brands and find this is the best product for defogging my swim googles. Spray on one lens and spread it to the other lens. So a little goes a long way.

Sent the wrong review earlier. This items is convenient to carry and does help to defog basketball goggles.

Nice but still have to reapply during my shift

Worked wonderfully but be carefull to follow instructions. Used on my race helmet with a plastic visor and had no issue with fog

There is supposed to be 4 oz of product in the bottle, but I was unable to make 2 -2 oz bottles for two swimmers. I’ve reached out to the seller to see if they will make it right. I’ll update my review if they do. Don’t package and sell as 4 oz if you aren’t putting 4 oz in the bottle. I believe this is a major issue in misleading and false labeling/advertising.Updated: The seller responded quickly and is sending a 1 oz bottle to make up for the 4 oz bottle being short of product. They did not address if they are going to be doing anything to ensure that the 4 oz bottles will actually contain 4 oz of product.

I highly recommend Spit. I'm an ocean swimmer and swim one to two miles three days a week. Without spraying Spit on my goggles, my lenses get foggy. With it, no problem! I recommend spraying it on and rinsing it off with water five minutes before putting on your goggles. Let it try and then put the goggles on. That way there will be no water getting into your eyes.

This product does 'work' when used as directed, which for swimming goggles, means spraying, then rinsing with TAP water right before you swim (NOT pool water - which removes it). Then yes, you don't get fogging for around 20-30 mins.Thing is, you literally get the same effect using any hand soap. Seriously, try it - put soap in your goggles, get it to buble, the rinse it out with tap water right before you swim (so it doesn't dry out), and it will be even better than this product.And unfortunately, all the other 'recommended' methods really don't work well at all. Seriously, try any of these any breath even a little on your goggles/glasses and they will instantly fog. I tried numerous times with all methods.Additional fails:- Spray on, spread, let dry, MINIMAL buffing, use.- Spray on, spread, let dry, rinse with water, useAvoid this product - it's literally a few drops of hand soap in water. In fact, I've been using exactly this using the YMCA hand soap into the goggle and then immediately rinsing with tap water right before my swim and it works a lot better than this product.Or at least try this method first before you use it on swim goggles.I wouldn't ever use this on non-swim goggles or glasses - as mentioned above, NO treatment method I used above (even done carefully) even resulted in the faintest antifogging when dry. Literally instafog with just the lightest breath.I'm pretty sure the 'magic' of this product is the reality that a tiny layer of soap followed by tap water keeps a thin layer of water on the goggle. Without that tap water right before you swim, the layer is useless.There is a product that I admit does work that I've tried. I wouldn't say it's perfect (far from), but actually DOES prevent antifog after proper application (smear & dry, GENTLY buff), which is the Z-Clear rub-on blue stuff. You have to apply a decent thick layer of that one, let dry for several hours+, then gently buff off, but that one actually works - if you breathe heavily on the treated surface, there is no fogging at all. And it doesn't burn your eyes, ever. No, I'm not paid to endorse Z-clear, and I do find the treatment method annoying as it doesn't work anywhere near as well when applied like <30 minutes before your activity.

Good anti-fog. Does the job. No eye irritation.
