Your cart is empty.Condensation occurs on the inside of your mask lens when diving, if not treated with a defog solution this condensation will create a mist like you see on the bathroom mirror after a shower. This layer of water makes looking through the mask lens impossible. Proper defogging of your dive mask lenses is vital to an enjoyable dive. Using a defogger from a company that has built its reputation on diver's optics is a no brainer. Use only the best from Sea Vision. Sea Vision's Defogger comes in a handy 2 fl. oz. (59 ml) spray bottle. Just a small amount sprayed on your mask lenses will keep them clear throughout your dive. This non-toxic non-abrasive defog is specially designed for the CR-39 lenses found on the Sea Vision Ultra, 2100 and 2000 Masks (see SKU's: SVNMUBK, SVN21BK and SVNM2BK). CR-39 Lenses are common to the Eyeglass Industry and require a Non-Abrasive Defog to be used to properly Protect-the-Lenses. This feature makes this Defog Product the Product-of-Choice for all Dive Mask Lenses.

This is the best mask defogger we’ve ever used. We’ve used it for years for snorkeling and diving. I like the ease of the sprayer instead of having to squeeze a bottle.

My 7-year-old grandson learned to snorkel this summer. We ordered this product to help with his mask fogging. It works. Our only mild complaint was that the bottle had leaked in shipping. We still had plenty left, however.

I was able to swim my 36 laps in the pool without fog on the goggles.

My Sea Vision mask still fogged up - even though I used it according to instructions. I will call the company and check.

My goggles were fogging every time I went swimming, and that was NOT fun - It ruined my days to the pool, because I could never see anything with all that fogging, and every time I wiped the fog off, it just came back. So I ordered Seavision Defogger, since it had the best reviews of all the defogging products. And now I know why! I sprayed once on each lens of my goggles, then rinsed them in the water. Make sure you do that to prevent burning. Then I placed the goggles on my head and swam - And I didn't get ANY fog!!! It lasts for hours, and it makes your days to the pool so much fun! And it makes the water CRYSTAL CLEAR!!! I would give this product 100 stars if I could! So if your goggles are fogging, THIS IS THE BRAND FOR YOU!!! I recommend it a million percent!!!

Don't have much experience with these types of solutions. I once bought something at Walmart that didn't work. I have used this SeaVision on my old goggles and had 50% improvement on the first use. Probably 90% after second application on these very old goggles. I also bought my wife new goggles. They fogged at 14 laps, but after initial use they did not fog for her even after her 25 laps.Pretty impressed with the results.
