Query regarding glass surfaces?

I’ve got a query relating to glass surfaces. I’ve noticed that
glaziers can fit special non-reflective glass to picture frames. I’ve
felt the surface of this special type of glass, and it is very very
slightly rough. It is perfectly clear and the picture can be seen
perfectly, but there is no glare or reflection visible.
I wanted to know whether or not this special type of non-reflective
glass "fogs up" in warm humid conditions. Perhaps the slightly rough
surface may prevent condensation forming? If a mixture of ultra fine
glass bead powder and clear acrylic lacquer (and lacquer thinners) was
sprayed evenly on a glass surface, this would result in a very fine
rough surface. Could this possibly prevent fogging/condensation on
the surface?
