Fog Eliminator prevents fog on optics in cold weather, moist environments or athletic activities. It can be used on eyeglass and sunglass lenses, camera lenses, sports optics like goggles and face shields, and precision optics such as binoculars and scopes.
The Fog Eliminator was developed as an alternative to conventional sprays or waxes. The Fog Eliminator soft cloth spreads a dry, invisible ultra-thin coating that absorbs moisture. Fog microdroplets are absorbed into the coating, instantly spread across the film's surface, and evaporate back into the air before fog can form. Each application gives hours and hours of protection, and the cloths are reusable 8-10 times.

Does work, as opposed to the impregnated Nikon cloth, which does not. A hassle to keep protected/moisturized, but haven't found anything that works better.
Absolutely useless . does not work on my canon VF. I don't know whose idea it was but it's just nothing but waste of money
Discovered that while hiking, can defog glasses lenses by wiping fogged lenses with balled up wipe. If just use a paper towel or similar, glasses fog up almost immediately.
