Understanding frame size

Understanding frame measurements is essential for achieving a precise fit tailored to your preferences. Thanks to a standardized system, finding the right size becomes straightforward.

When considering frame measurements, it's important to focus on three key dimensions: lens width, bridge size, and temple length, all measured in millimeters. These measurements ensure a comfortable and proportional fit that complements your unique facial features and style.

EYE

40 - 62 MM

This eye measurement is the horizontal width of a single lens. Typically ranging from 40 to 62mm, with the average size of 49 to 51mm. For sunglasses, consider increasing your average by a minimum of two millimeters to account for the larger frames.

BRIDGE

The bridge measurement refers to the gap between the two lenses, with sizes ranging from 14 to 24mm and the typical size falling between 18 and 21mm. For those with a narrower bridge, choosing a frame under 20mm is advisable. Frames equipped with nose pads offer adjustability, ensuring a a better and more comfortable fit.

Temple
