Are the Blue Iridium lenses fine for night?
generally, iridium lenses are meant for daytime riding, as they all offer varying amounts of UV light filtration (fire iridium having the highest I believe).
For night riding you'll want a more clear lens (HI yellow, clear, or pink will do fine, even Persimmon)
blue should be ok. i've ridden at night with black iridiums and it was fine but i prefer my yellow lenses in low light. also, ALL oakley lenses block out 100% of UV light. the previous answer confuses blocking overall light transmission with blocking UV light. UV light is invisible to the human eye and any quality lens should block out 100% of UV.
