Frame size is determined by the three key measurements found inside the frame arm: lens width (from 31-60mm), bridge width (from 12-31mm), and arm length (from 115-155mm).
Lens height is essential for multifocal prescriptions, such as Progressives, which require a minimum measurement of 28-30mm. They are also recommended for Rx sunglasses.

Timelessly cool, the Soprano's rounded frame complements small to medium faces and angular features, while the keyhole bridge sits comfortably on wider noses. The slim, brushed metal arms feature spring hinges for comfortable all-day wear, and the iconic Derek Cardigan mathematical symbols at the tips.
