realllyyy does the job.i bought this antifog spray for my swim googles since they were getting foggy all the time... and one spray in each side they lasted the entire practice session, and the entire day actually. its a really good quality product.

It does what it says for fog. No fog for the first two days. Started fogging slightly in the third day as expected.The issue I have is it increases the reflection and streaks on my otherwise spotless glasses. So, decide on what you prefer :)By reflection I mean reflection of my cheeks and eyes. Especially visible outdoors.

It wears off within a day or two, but works really well

Very effective in preventing fogging of specs once you get out of AC car

Basically involves spraying it over the glass and wiping it dry.Process is a bit cumbersome (although it may not sound like it)Biggest issue is the anti fog effect is very short lived (one day?) A minor smudge on glasses will cause it to start fogging again, which will slowly dilute the surrounding antifog stuff.I have not checked it in real tough conditions like PPE (ordered originally for this) but seems ok for daily use effectiveness wise. Eg glasses won't fog after air-conditioned car ride on the morning after application. Can't say this for evening.

Good awesome products i used it when i play football game its very usefull

The coating only works if ur glasses are dry. One single drop of water or went in rain makes the coating to be removed easily. Doesn’t works in rain and also if u use this while in rain ur visibility becomes blur, u cant see anything if it is exposed to rain or water.
