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.
These classic geeky-chic frames from Derek Cardigan accommodate broader faces requiring extra long frame arms. The winged-out rectangular style flatters soft features and rounded, tapered jaws, while the iconic Derek Cardigan math symbols sit at each temple for a flash of vintage nerdy cool.
