Review on Nano Anti-Fog Eyeglasses Cloth: Keep Your Glasses Crystal Clear with this Reusable Dry Cleaning Cloth by Myel Shuey

I've been using this brand of fabric for a while to keep glasses from fogging. I have two. I have a third one for my daughter. She has the same problem with fogged up glasses when wearing a mask. This stuff really works. Wipe the windows and they won't fog up for quite a while. They really do solve a huge problem. If the glasses fog up, there is a chance that you will touch your face to remove the fog. I highly recommend this product.
