According to www.defogitworks.com, “It’s the anti-fog solution used by the military worldwide to stop fog on glasses, goggles, safety glasses, shooting glasses, face shields and other optics.”
Regardless of your political views, if the US military is going to use this anti-fogging compound, then there has got to be something to the claim.
After receiving our first shipment of Defog It, I felt letdown by the extremely small size of the package contents. I was never was very good with Imperial units and I was expecting diluted product in an 8-oz or 16-oz pump spray bottle. So maybe this surprise is really a good sign. Concentrated formula, small and portable — different is good, right?
Nanofilms states repeatedly that this product is safe for any type of lens or optic. I cannot independently confirm or deny this statement as fact, but I can say that there appeared to be no adverse effect on any of the safety glasses, goggles lenses or face shields I tried it on. This includes mirror lenses & photochromic lenses.
The test I setup was one that I felt was best representative of our clientele and readership. Strenuous work with a need to move from indoors to outdoors and back. We had the heater set at 75 in the warehouse with all doors closed and my computer said it was 29 degrees outside with no breeze. After working up a good sweat I stepped outside. The glasses I had chosen were the Sperian Fulcrum with a clear lens. I picked this specific pair because they fit extremely close to my face and allow very little natural circulation that would normally help reduce fogging.
After freezing my butt off for 30 minutes, there was no fog on the lens – Even when I cupped my hands over my mouth directing my breath to the glasses. So I headed back in with my now very cold safety glasses and proceeded to work myself back into a sweat. Still no fog.
In a nutshell I have to say that Nanofilm’s Clarity Defog It is the best anti-fogging product that we have found. The product is simple quick and easy to use and it is small enough to put in any tool bag, shirt pocket or jacket without being obtrusive. Although, it is easy to lose!
I’m giving this one 4 stars out of 5. If the price were a little lower and the product bottle and contents slightly bigger, this would easily earn a 5 out of 5. The fact is, however, Defog It worked wonderfully for our test. And you know what? If its good enough for the military, its good enough for me!
