Has anyone tried these for a longer period in different light conditions? The lens tint description is somewhat misleading, as it says "activated 10% - faded 60%" transmission, while for other photochromics/transitions, the descriptions usuall give the range of transmission between the two extreme values. I'm just wondering if the clear/BI lens has gradations of shading or just two positions (either 10% or 60%, but nothing in between). And do they really work as well as a regular Black Iridium lens in bright sun? There was a Bikeradar review of them that claimed they were nowhere near as dark in their activated state.
