I currently own a pair of M Frame Heater, red iridium sunglasses. I use to have a pair of the Blue iridium, i use to wear these in the winter time, when there is snow on the ground and the sun is out, that just kills my eyes. I found that the Blue iridium was darker then the red and it protected my eyes better in those conditions. I went to Oakleys website to order another pair of the Blue iridium M Frames, but they didn't have them, but they have the Ice iridium. My questions is, is the Ice and the Blue somewhat the same lens ? Is the Ice iridium dark enough for me to wear to prtect the brightness of the snow and sun ? Thanks and sorry so long !
