The edger clamp is a black rubber so it appears to be the black dye of the rubber itself imprinting itself onto the antifog coating. Beyond this, you have to be incredibly careful marking the lenses up (you can only mark them up on the front side) or even cleaning them because the backside coating is damaged very easily. The specific coating in question is the Essilor Anti-Fog AR. I believe the Crizal Avance w/ Optifog doesnt have these issues, its more like a traditional AR, correct?
How do you guys edge these lenses? Or do you not even bother and send it off to a lab? Also, how do you clean these lenses?
