Every time when I come to the kitchen or the place where the temperature is higher than the outside, my eyeglasses lenses are full of fog soon, I really hate that! Is there a special coating for preventing the fog?

I have ever heard this kind of coating, such as "golden coating","diamond coating" or so, but I can tell you the truth, no one will be effective as the ads says, if you come a place where the temperature is higher, I really suggest you can put your eyelgasses in the water, or just wipe the lenses when there is fog on them, that's no much too troublesome
