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.
The Cyllene glasses from Derek Cardigan deserve a double-take. The brilliant semi-rimless design marries the D-frame silhouette with angular styling on the metallic upper rim, which makes these frames look stunning and contemporary. Featuring acetate material on the temples, this pair is complemented with adjustable nose pads and spring hinges for added comfort.
