Like the last reviewer said, the Fire lenses are a little bright for the highest intensity light conditions. My eyes got a little fatigued while driving thru the desert on a really sunny day--lots of reflection off the light colored sand and road meant a LOT of bright light. However, I threw on some of my older really nice brown lenses without the reflective mirror (they were Smith's, which are great too), and the light intensity was MUCH stronger without that reflective iridium coating! Great all around lens, I really like the Fire. Cool look too, of course.
