I have to respectfully disagree with this comment. Pink iridium is perfect for flat light conditions. I don't know what percentage of light they let in, but in my experience, they are excellent. I have used my oakley aframes with pink iridium a half dozen times this year. Three with flat light/snowing, once with medium light (partly cloudy), but sun not in face, and once at NIGHT. I live in NH and bought them specifically for flat light conditions. They fit that need perfectly. They were even excellent at night with snow coming down. Yellow lenses give me a headache in any conditions other than flat/no light. I know that we are all different in likes/dislikes, but pink iridium is just so easy on the eyes and provides good clarity of vision, for me, in no light to medium light conditions. That seems like a pretty broad range for one lens, imo, which makes it one of the best choices in the east.
