The coating, a thin sandwich of transparent plastic and layers of silica particles too small to be seen with the naked eye, works by attracting water more strongly than the glass does. This flattens each of the water droplets, smearing them over the surface in a see-through layer.
"The coating basically causes water that hits the surfaces to develop a sustained sheeting effect, and that prevents fogging," said Michael Rubner, a materials scientist who led the research.

what were they using on anti-fog ski goggles four years ago then?
Other coatings exist, but wear off over time or have other drawbacks. I don't what they're using on goggles, or if there's something that works better on them because they're smaller or what. One of the cool things about this technology is that it will work on harsh applications like windshields.

Detergent is what they use, me thinks.
An old trick for your shaving mirror. Smear some soap on the glass, which will stop it steaming up. But you need to keep on applying soap every now and again.
