GEAR AID Sea Drops Cleaner and Anti-fog for Dive and Snorkel Masks, Clears Up Dirty, Foggy Lenses, 1.25 fl oz

Worked great. You can just spit on your goggles too. Not snot, but just saliva and rub it around just the same. My wife bought these. We took them to St Croix and snorkeled 10 beaches in 7 days. Four of us. These drops do keep your masks clear. By the way, that is a relatively affordable trip. If you can get to St Croix or Puerto Rico, and you aren't scared of just being around people, who are very friendly, you can just rent a car drive yourself around, beach to beach and there is plenty of good food to eat all over too. The drops work. Winter of 2024-2025 we still saw plenty of tropical fish and some corals at St Croix to show to our children, it was a blast. They are not all dead yet.

We are divers, and this is the best anti fogger we've used. Super effective with one or two drops. Keeps it fog free all dive as long as you don't take off your mask and get it wet.

This stuff works great for snorkeling. Use it every time you go out, well worth it. Don't use your (greasy/oily) fingers to rub it in though, just add a little water and swish it around and then rinse just before putting your mask on. There are several other hints to prevent fogging (like using toothpaste and toothbrush to clean glass-but not plastic) that you can find online with a simple web search.

This requires daily usage. You apply a clear thick goop and smear it all over your lenses and rinse it off gently. A thin layer remains behind and is very anti fog. However, it's very delicate. If you take a cloth to dry the lenses, then the goop layer will be removed and they'll no longer be anti fog. It'll work on glasses and motorcycle shields, but only if you can follow those directions. I find the goop too delicate for my use. I'd rather have something I apply and that will form a durable anti-fog layer to last at least a few days, maybe a week or more. This is not that. I don't fault the product though, I imagine it is well suited for Snorkel Masks that you can dunk in the pool to rinse them off.

I'm all for supporting my local dive shop, but this is just easier and such a cost savings to get a few packs here Tried baby shampoo, but just don't have the same luck, and this is good for a long time so easy to go. Small enough for carryon and convenient, what's not to like

convenient and worked great

They worked ok for a short period, maybe half an hour before no noticeable effect remained & reapplication was needed, I used with two different masks (glass), in freshwater. I haven't yet found anti- fog drops that seem sufficient, so maybe my expectations are unrealistic.

Great product. Works better than most. Dive buddies used all of mine on the last trip!
