Does anyone have a good solution to keep sweat away from your ridin' glasses? As the sweat dries on the glass the visibility gets seriously bad and after a few uphills and downhills it becomes a bit tricky. Are there any good solutions out there? Stopping and cleaning them is not an option in a race. The ones I use are some cheap torpedo 7 so it may be crap design?

Suggestions welcome.

Cheers!
