Katie 218



Katie posing in yet another cornerstone in my collection - strikingly beautiful glasses made by Christian Olivier. The frame is chic but it's the lens choice that sets these glasses apart. Their first owner apparently made a deliberate choice against the newly invented high index lenses. Instead, she chose for myodisc lenses of the "Formlenti" type, an innovation of the early 1970's. Depending on frame size, a myodisc lens was used when the prescription exceeded -12 or -15. A traditional myodisc lens consists of a central "bowl" with the visual correction needed, surrounded by a carrier lens which can be plano but sometimes positive to further minimalize lens thickness at the rim. The disadvantage obvious: everyone could easily recognize that myodiscs were a final remedy. The invention of Formlenti changed that completely. Formlenti don't use a circular bowl. Instead, the carrier lens follows the shape of the frame so that the central part with the visual correction is in harmony with the design of the glasses. The first owner of the Christian Olivier glasses had a prescription of "only" minus ten but she chose Formlenti to put an extra accent on the chic frame. A classic example of "showing rather than hiding" which is the right attitude, recommended to all high myopic ladies.
