I was at the deer convention in bloomington this year. I bought some of this stuff called Emerald sStar. Anti-fog& cleaner, anti reflective coating, cleans & prevents fogging on glass and plastic lenses. I no when he showed me it, he put it over a vaporizer and it didn't fog.

Seem to work pretty good the first few times I used it. Then used it again and I remember my glasses were fogging up a little. Maybe I didn't put it on good enough? I'll try it again this week end to recheck!

I use to wear contacts a long time ago. Does anyone wear contacts inreally cold weather? Do they work ok or do yours eyes tend to get blurry?

thanks
