You'd think there would be more info online about Oakley's lenses but I can't find much. I can only offer my anecdotal evidence. I have a pair of Smith goggles with both the blue sensor mirror and gold chrome lens. the blue sensor lens is much better for all around conditions. But, they're not quite dark enough for cloudless bluebird days. That's when I break out the gold chrome lens. The blue is MUCH more useful.
Thank you, that's exactly along the lines of what I was looking for. If you've been to Burton's site, they have a shit load of lens options, but they also have that simulator that shows what the differing conditions would be like for park/pipe/backcountry for a blue bird/overcast type of day. Pretty bitchin, but I wasn't sure if that applied to manufacturing lenses of those colors, or just Burton's.
