I can see your problem, though I don't have glasses. The balaclava is really only for extreme cold. It makes your head warm up really fast. Even if it's -20 degrees, I end up sweating after 10 mn! Especially with the helmet on the top of it. So I'd say, don't wear it unless you really think your cheeks are going to freeze. If it's not so cold I usually put a scarf around most of my face, if it's well tucked into your jacket it's easier to adjust. And, of course, a tuque. Otherwise your ears will fall off.
