I tried to remove the anti-glare coating with rubbing alcohol -- it made more scratches.
I tried to use toothpaste and an electric toothbrush -- It did nothing.
Then I remembered that my sweat had made the coating cloudy. So I made a salt solution (dissolve a teaspoon of table salt, NaCl, in a cup of water) and used the electric toothbrush. It removed the coating, but several applications were necessary to get it all. It might be a good idea to remove the lenses from the frames, if possible, (I didn't) as the salt solution may be corrosive to the frames. At a minimum thoroughly rinse the glasses.
