are two pictures with differeI have a pair of Splices with a black irridium lens, and a friend has the Dark Grey one.
The Black Irridium is a pretty handy lens works in a lot of lighter conditions and it looks great.
It is an amberish colour when light is coming from behind the goggle (not worn) and a dark silver mirror when there is only light from the front (worn of course).
The Dark Grey polarized is really quite dark and only handy for days when the sun is attempting to melt all the snow of the mountain, and they look just black when worn.
Here are two shitty pictures I just made with different lights.
