When I'm wearing sunglasses I've always been able to ride without any problem. The only time I didn't wear them was on Chang (SFKK) because the OTSR pressed against the side of my head right where the frame of the glasses was so it hurt. I had to hold my glasses in my hand.
When I wear glasses on MF, I make sure not to turn my head because I'm afraid the wind will pull the glasses off.
