I've started to look at the packaging specifically for this. It's interesting to note that, for instance, a lot of goggles designed for PWC use have no impact resistance. In looking into to this I figured that given a PWC's performance that impact resistance would be a good thing in goggle. Apparently not. I notice my Barz state impact resistance, but the Dirty Dogs I've been wearing for awhile would most likely push the lens into my eye if it took a hit. In fact I lost one of the lens in a minor whack during a capsize. Just something to look at and consider. (and yes I do own a PWC...)

I've almost thought that buying a pack of shaded polarized work shade from Home Depot might be a good solution - impact resistance, and cheap (don't worry about losing them, just grab another out of the pack).
