Thank you.To answer your questions, the number under the earsocks have nothing to do with the colorway or model of the glasses. They didn’t put skus on the SW2.0 frames so there really is no definite way to know what lenses that frame came with.
However, here are the colorway options that were available for a silver SW2.0
That is super Info.
I thought the last owner removed it my using a scotch Pad to clean the frame.
So that number means nothing?
