Review on 🔥 Clear Vision Guaranteed: ZEISS Fog Defender System Anti-Fog Spray for Glasses - Includes 1 Spray Bottle and 1 Microfiber Cloth! by Lautaro Olive

Why buy something like this? Because you want me to have anti-fog quality. Well it isn't. I'm so sad to say this, but no matter what I try and how many layers I use, it only takes a few minutes. I want this product to work but I only have to give it one star because it's the only thing it's supposed to do and it doesn't. (Packaging is good, easy to use, no smell, etc. All is good.) To be clear, there seems to be a film forming on the lenses that prevents them from fogging up. Just saying if you are looking for something to prevent fogging when wearing a mask then this will not help. However, I think it helps if you move from a cold place to a warm one. Some people say that this product depends on the coating on your glasses. So this might work for you
