I never ride for more than a block or two with my visor flipped all the way up, even with glasses on, especially not at road speed. Too many bugs, stones, other debris to hit you in the face. I may crack it open a quarter inch or so, but never all the way open, defeats it's purpose.
To me, having to put the glasses on through the visor opening is not big deal, and like I said, lets the engine warm up for another 30 seconds or so while I'm fiddling with everything too get it all comfortable.
