WORKED FAIRLY WELL FOR ME
I (as I am sure with others) kept having my glasses fog up when wearing a face mask. I tried this spray, and it does work. BUT .. after about 2 hours, it started fogging up again (but just slightly). I mainly use it when we have to go out to replenish groceries. That time frame works OK for me, as we are in and out of the car, so I can respray if needed. I am satisfied with the product. The tiny Microfiber towel is handy and seems to work well. So if you only need a few hours, I can recommend this anti-fogging spray for your glasses.
