Myodisc lenses were - and are - used when the Rx is too high for ordinary or even high index lenses. The rims become too thick and the glasses can't be folded up. Traditional myodisc lenses consist of a central "bowl" with a diameter of 25 or 30 millimeters and the Rx needed by the wearer, surrounded by a plano or magnifying carrier lens. Formlenti were invented in the early 1970's to obtain a more satisfying aesthetic look. Here the carrier lens follows the shape of the frame. This can be seen clearly in this fine portrait of Simona.
