Iris 161

Concentrated posing by Iris in contemporary myodisc glasses from China. The "Formlenti" effect is clearly visible. Only the central part of the lens has the extreme Rx required. It's surrounded by a plano carrier lens. Note the sharp demarcation between the central part and the carrier lens and especially the way this demarcation neatly follows the shape of the frame.
