Formlenti were an invention of the late 1960's. The aim was to provide a more aesthetic alternative for traditional myodisc lenses with a circle shaped "bowl". The demarcation between the "bowl" and its surrounding carrier lens is clearly visible in this fine portrait. A tiny image of the partially wooden medieval house in the background can be seen in the "bowl". By contrast, the positive carrier lens shows a reflection of the model's skin. Jennifer's amazed look is priceless.
