Did not work to keep glasses from fogging
I purchased these to use on my glasses due to fogging up when using a mask & when I wear goggles for snowboarding. Unfortunately, they were 0 for 2. My glasses still fog when I have to use a mask. They also did not prevent them from fogging when I used my goggles for snowboarding. I am legally blind without my glasses, but even after using the cloth as directed I had to ride without my glasses as they fogged up so bad I could see better without my glasses.  Very disappointed with this product!
