Review on 👓 COOSKIN Reusable Anti-Fog Cloth for Glasses - Lasts up to 48h, Odorless AntiFog Dry Wipe, Antifogging Lens Wipe - Ideal for Eyeglasses, Goggles, Screens - Includes 2pcs by Kim Marin

The anti-fog coating they apply doesn't seem to last 48 hours but I'm not sure anyone can last 48 hours between lens cleanings. Not perfect. In heavy fog (when entering a humid room after sub-zero temperatures), they still fog up, even though this is a more transparent fog. On most normal occasions walking around the office with a mask on, my lenses stay fairly clear. Cheaper than laser eye surgery and more effective than without glasses. Definitely worth the money. I will be ordering a few more to keep in different areas.
