Glasses with lotus effect coating

They stay fog free (of course it is warm now, perhaps not so good in winter when you come in from the cold into a warm room) and relatively dry on the shower. The water pears off like from a duck’s back when you shake your head a little, some smaller droplets remain. Not perfect, but good.

I’ve bought eyeglasses in the US for years and never heard of this type of coating. Is this available in the US? Is it perhaps called something else here?
