I tried, a lot. Wasn't able to get this to work.
I used this at work straight for two months hoping it'd get better with time as a film built up over my glasses. I looked up multiple application videos from both the company and third parties demonstrating the product. Unfortunately, in my experience, this only reduces fogging slightly and does not really stop it or diminish it enough to be useful; I still find myself unable to see my screen and adjusting my mask constantly at work.
