Optic getting foggy
 

Have an EOTech 512 on my ar that I carry as a duty rifle, when I pull the rifle from the car it's cold from the a/c and the lenses of the EOTech fog up. What can I put on the lenses, if there is such a thing, to reduce how bad it fogs up or even eliminate it all together?

There are all kinds of anti-fog products for glasses and windshields. I just don't know if they would be safe for the optic.
