The Panto is a model that per definition should be rather small. All models are available in #47, which basically is the “one size fits all”. Some of the models are also available in #45 and #49. The number corresponds with the width of the glass in millimeter. The critical parameter of the TRUE PANTO is the rounded (although not circular) shape of the optical glass, stricktly designed by combining the given 6 radiuses of panto. The rounded, although not circular shape, and the smaller sizes contribute to the light weight and thin smooth edges of the glasses.
The Panto design is PROBABLY THE WORLDS OVER ALL MOST RECOGNIZED SHAPE AND DESIGN OF GLASSES.
Due to its ocular shape, it is a natural fit to the majority of faces and users of glasses.
