I have a special edition of these where the frame has a spring hinge and greyish earsocks rather than white. I bought them with the titanium clear and like them very much for low light. I had a friend who had a pair of titanium iridium lens that I bought from him. Strangely I really don't care much for the titanium iridium color, but love the clear which seems to be opposite of everyone I've seen on this site. Any way definatley one of my top three pairs
