So the Radar EV lenses are toric. But like a Turbine they seem to be higher base curve than fuel cell, or gascans. So I measure them as a 7.25 horizontally. The curve looks totally at home here, the bevel I put on them is a machined 8 base curve. So the fit in frame is phenomenal! Here is a before picture of the fmj, and an after photo of the cobalt. @Brian Nickell thanks for letting me help you on this +red Iridium project. They won't touch your lashes bro occasionally on certain frames, a person with a smaller nose bridge, or an "Asian" facial structure, and long lashes might bump, not on these!
