ULTRAVUEDynamic Labs Fog Stopper - Stops Fog on AR Lenses and All Lenses

Used this in my airsoft goggles and shooting glasses. I add some before the match and after each match. It keeps the fog away for the majority of a round (30 min) but must be reapplied. I ended up selling out a bit extra for an ex-fog unit. Now that is definitely worth looking at. This solution is a great option for the meantime. Great value, fits in glasses case, great quality (better than rainx!!), easy to apply, no eye discomfort, versatile.

Works very well! Use it on my bike helmet shield to stop it from fogging up while riding to/from work.

This one really works! I put a few drops on each eye befor playing sports and what used to be a super foggy experience turned out to be quite nice!

Make sure your glasses are clean and dry before applying .I'd suggest wearing a mask and gloves while applying this substance, the chemicals seem to off-gas into the surrounding environment until it sets/dries. I personally prefer, while using gloves, to use a finger to spread the solution across the lens with light pressure until it starts gelling up and becoming tacky. Then, I'll use a clean microfiber cloth to spread the coating around in swirls so it's even. Then, I'll use a hairdryer to blast it with warm air to set it quicker. If your hairdryer only has a hot setting then do it from further away so as to not warp the lens.The result is quite impressive where breathing on the lens would not create any fogging.However, after waiting a few days to make sure it set completely, I rinsed one lens under low pressure cold water (no soap or cleaning solvents), and the coating completely disappeared. I think it either dissolves with water or doesn't adhere particularly well to my lenses. I'm a person that normally cleans my glasses with dish soap and water so this coating isn't for me, but it might work for those that clean using a micro fiber. I haven't tried that yet.

The first application did not go well, but it could have been I did not apply it correctly. Finally got the glasses to not fog, but did not last the whole nine hours of work. Again, it could be something I am not doing correctly, or something else going that I am unaware of at this time. However, the glasses did not fog up for six hours. I was happy with that part.
