How do you guys deal with it? I ride through some bloody frosty gullies on the way to work, and have about 30 seconds to a minute of frost building up on my visor. All I seem to be able to do is flip the visor up enough to see under it, but then my eyes water ridiculously after about 10 seconds, negating the whole being able to see concept! Wiping the visor only helps for a few seconds, then teh frost builds again, and then the visor is all streaky. It's annoying, as it's only about a minute at a time I get the frost, then it disappears as I ride out of the gullies. Regards, Andrew.
