This document specifies a measuring system for spectacle frames and related terminology. It is applicable to spectacle frames with fronts that are intended to be symmetrical.

NOTE

Minor asymmetry of only the nasal bearing surfaces has been included in this edition. Since such asymmetry does not affect the lens shapes, only the definition of bridge height is affected, having an amendment in its note 2 to entry.
