"Get the lenses with a good AR, anti-reflection, coating."
Did that, actually, i suspect the hydrophobic layer to be making the OP DROPS anti-fog uneffective, since it needs a surface to grab onto, I'm planning to visit the shop and check unfiltered lenses if they do any good with anti-fog stuff, if they do, 250$ goes to waste
But i'm also considering using some kind of pump to pump air through some thin air pipes into the goggles, it would solve the problem.
