There has been an H.I Yellow Square Wire 2.0, Half Jacket and M frame with this lens. Have owned Both H.I. lenses in one point in time over last 7 years, The Iridium just adds a light reflective to it to take edge off of glare, I personally can't wear the H.I. Yellow if the sun is out it's too blinding only if it's overcast or at night as it lets in a lot of light. Here is Oakley lens tint chart Oakley Sunglass Lens Tint | Oakley.com
