All joking aside, it's threads like these that make me realize even more benefits that come with wearing contact lenses; not only am I afforded UV protection, but they also shield my eyes incredibly well against colder winds while riding. I feel my eyes still water the same amount however, my eyes remain far more comfortable when riding with contact lenses in, than without, especially on the slopes. Obviously you wouldn't buy/wear them for this purpose alone, I just thought I'd share my insight (or rather lack thereof).
