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".
