A bunch of years ago when working in a bike shop I picked up a couple of pairs of original Frogskins. one pair had a purple iridium coating and the other had an orange iridium coating on the lenses. The purple pair had what I remember being a grey base lens and the orange pair had what best can be described as a Rayban green base to the lens. I'm going off memory and could be wrong but I really liked the base tint of the orange pair. Is something along this lens still offered? TIA
