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 Titanium Mastodon is as sturdy as its Ice Age namesake, but that's where the similarity ends! A contemporary take on the D-frame style, the design blends an acetate frame, delicate metal detailing at the temples, and ultra-lightweight materials for a statement piece that flatters softer features, rounded jaws, and narrower foreheads. The frame’s slim, flexible arms are a good match for smaller to medium faces.
