Yeah, Slate is really transparent. That looks a bit to Blue for Prizm Slate though. I'd call Prizm Slate a lighter version of Prizm Daily. Interested to see what this is.
Prizm Argon snow is Prizm Jade but with the Prizm Garnet base tint. The old Prizm Jade snow was the only iridium lens that had Prizm Rose base. This season they got rid of Prizm Jade snow and now green mirror is Argon Iridium.
I like that they are improving things but being a sunglasses guy, I wish they would incorporate more snow lenses into regular sunglasses frames.
They have Argon at myblocal store and honestly, it reminds me a bit of blue iridium. Sage gold is a decent replacment for gold iridium. Prizm HI pink would work for pink iridium.
At least to get some variety rather than the same 5 lense in eveything
