Glasses Frame Size

Frames are sometimes offered in more than one size. Your choice of frame size is a personal preference (some wearers prefer a slightly larger or smaller size of frame). The frame size is denoted by 3 sets of numbers e.g. 52/19/140. The first measurement is the lens width - the horizontal distance across a single lens (excluding the frame) in millimetres at the widest part of the lens. The second measurement is the bridge size - the horizontal distance (in millimetres) between the lenses at the narrowest point. The second measurement is the arm length in millimetres.
