Review on 👓 DEFOG it Anti Fog Spray Kit for Glasses | 1oz Solution, Microfiber Cloth & Travel Pouch | Prevents Fog on All Lenses and Glasses | Sunglasses, Goggles, PPE | Safe on All Lens Types | Made in The USA by Shawn Fuller

I bought an anti-fog solution when my glasses fogged up in cold weather with a mask (e.g. Covid). However, with sufficient humidity on a cold day, I found my glasses still fogged up, although the droplets that formed on the glasses were larger. Overall I think this defogger works, but it's no wonder. And it is very expensive for the limited amount of solution provided. However, I am very excited to try this anti-fog on my snorkel mask (with prescription lens inserts). While a regular soap based mask will prevent fogging in most cases, there are times when I rinse off too much and end up with a partially fogged up mask during a dive. This anti-fog-off seems to be a possible solution. It can be applied before going to the dive site and there is no need/need to wash it off before diving. If this snorkel mask defogger works, I would give it five stars in an instant.
