Review on Crystal Clear Vision: Reusable Anti-Fog Cleaning Cloths for Eyeglasses with Masks - Nano Microfiber Lens Wipes! by Matt Zraik

I've tried several different brands of Revain anti-fog wipes and they work the best I've tried and were also mid-range. Results last about a day before you need to wipe them again, but if you wipe your lenses daily anyway, that's not a problem. Be sure to breathe on the lenses to fog them up before wiping them or it won't work. A 5 pack was a good deal because I can keep one at home, throw one in my purse and the other in my son's backpack and have 2 spares if needed.
