Three edited versions of the same portrait. Here Sandra is posing in another pair from the parcel sent to me by Stephan from Bavaria. The lenses are the traditional "Kreislenti" myodiscs with a circular "bowl", Rx minus twenty. Note the double image at the corner of the model's left eye. This effect is created by the slightly positive carrier lens that surrounds the bowl with its extreme prescription. The inner part of the frame is orange and some of this is visible through the right lens(es).
