Transitions Vantage first impressions: the good, the bad, and the ugly.

maybe they are a defective set? all i know is i was splitting wood for 3 hours this weekend in direct sunlight and it took forever to transition

Huffam..in Homer, Alaska..? My first thought was that maybe it was because your latitude is farther north and therefore you were not being exposed to as much UV. But I really don't know. I found this very technical white paper on "Factors affecting surface ultraviolet radiation levels in the Arctic", but I don't see that it explains why your Vantage lenses "took forever to transition" even in "direct sunlight".
