Review on Fog Gone Anti Fog Wipe: Reusable Microfiber Cloth for Crystal Clear Vision on Glasses, Electronics, Masks, Screens - Streak-Free Lens Cleaner (1 Pack) by Michelle Langley

This little cloth absolutely works. I wear reading glasses and they always fog up with the mask. I followed the directions by cleaning it (a little dish soap and water), letting it dry, wiping it down with a regular microfiber cloth, and then applying. I rubbed quite hard, but not nearly as hard as the negative reviewers (some said they were afraid your lens would pop out). I can wear them for hours without a mist and in my regular mask without a nose clip. My 9 year old just got prescribed reading glasses and now wears a mask to school. I've literally spent hundreds trying to find masks that he finds comfortable and I was really scared to add glasses to the mix. I'm so relaxed I ordered one for each of us and also one for his backpack. I saw a review that said the bag is not resealable. That. There is a strip at the top that closes, but be careful not to cut it when you open it. Good product!
