Bests & Worsts Reviews from Amazon

I applied the product to my glasses at 6 am and it has now been 3 hours. It has worked, so far. The product website says that it will work upto about 24 hours. The directions for use are not on the product. You must go the manufacturer's website. All you have to do is clean your lenses, clean with a microfiber cloth. Then you spray both sides of your lenses and let it sit and dry to a haze. Once dry you just buff the surfaces of the lens. I applied it just before ironing some clothes for work. I am very pleased. Now I can carryon a conversation with my mask on and I can still see the other person. I will update as the day progresses. So far, I highly recommend this product. Update: The Anti-Fog kept working beyond 24 hours. I went two full days and I stayed fog free. I was prepared to be disappointed, but I am far from that. Buy, buy, buy.
