Full title and description

Ophthalmic optics — Spectacle frames — Lists of equivalent terms and vocabulary. This International Standard defines commonly used terms for spectacle (eyeglass) frames and provides lists of equivalent terms in multiple languages to promote consistent terminology across the ophthalmic optics supply chain.

Abstract

ISO 7998:2005 specifies vocabulary and equivalent terms used for parts of spectacle frames. The standard gives agreed definitions and lists matching terms in English, French, Russian, German, Italian, Spanish, American English, Japanese (with phonetic transcription) and Chinese. It is intended to reduce ambiguity in design, manufacturing, specification, documentation and trade of spectacle frames.

Scope

ISO 7998:2005 defines commonly used terms relating to frames for spectacles and eyeglasses and lists equivalent terms in several languages for parts of such frames. The scope covers vocabulary for frame components and related nomenclature used by manufacturers, suppliers and clinicians; it does not cover measuring systems, formers, edging machines or protective goggles unless explicitly indicated.

Key topics and requirements

• Standardized definitions for spectacle-frame parts (e.g., rim, bridge, temple, end piece) to ensure consistent usage.
• Lists of equivalent terms in multiple languages (English, French, Russian, German, Italian, Spanish, American English, Japanese with phonetics, Chinese) enabling international interchange of terminology.
• Vocabulary intended for use in product specifications, technical drawings, procurement documents and translations.
• Clarification of terms to avoid ambiguity between regional or trade-specific expressions.

Typical use and users

Used by ophthalmic optics manufacturers, frame designers, optometrists/ophthalmologists, eyewear importers/exporters, standards committees, technical translators and procurement/specification teams. It supports consistent product descriptions, labeling, technical documentation, translation and regulatory submissions where precise terminology for frame parts is required.

Related standards

Replaces ISO 7998:1984. Often adopted nationally or regionally as EN ISO 7998 / BS EN ISO 7998 and included in the corpus of ophthalmic optics standards maintained by ISO/TC 172/SC 7. Related ophthalmic standards on spectacle measurements, testing and labelling (published under ISO/TC 172/SC 7) are typically used alongside this vocabulary standard.

Q: Who typically uses it?

A: Manufacturers, designers, clinicians, translators, procurement teams, standards bodies and regulators involved with spectacle frames and ophthalmic optical products.

Q: Is it current or superseded?

A: ISO 7998:2005 (Edition 2) replaced ISO 7998:1984. As published in 2005 it remains the current edition (confirmed in national adoptions such as EN ISO 7998). Users should check national standards bodies or ISO for any subsequent revisions after 2005 before applying it in new specifications.

Q: Is it part of a series?

A: It is not a numbered series item but it is one of the standards produced under ISO/TC 172/SC 7 (ophthalmic optics). Related standards in that committee address measurements, testing and other aspects of ophthalmic optics and eyewear.
