Full title and description

ISO 8320-1:2003 — Contact lenses and contact lens care products — Vocabulary — Part 1: Contact lenses. This part provides a standardized vocabulary and definitions for terms used to describe contact lenses, their physical, chemical and optical properties, and symbols commonly used in related standards and technical documents.

Abstract

ISO 8320-1:2003 identifies and defines terms applicable to contact lenses and contact lens care products. Its intent is to provide a consistent vocabulary for use in the development, testing, labelling and regulation of contact lenses and related standards, supporting clear communication between manufacturers, laboratories, regulators and clinical professionals.

• Number of pages: 37 pages.

Scope

This part of ISO 8320 establishes agreed terms and definitions used for contact lenses (including related dimensions and symbols) and provides the vocabulary referenced by other international standards and technical documents in ophthalmic optics. It covers terms describing lens materials, geometry, optics, surface and chemical properties, and general descriptors used in manufacturing and labelling. The standard was later incorporated into and superseded by the broader ISO 18369 series addressing contact lens vocabulary, classification and labelling.

Key topics and requirements

• Standardized definitions for contact lens physical, chemical and optical properties (e.g., material type, water content, modulus, oxygen permeability).
• Symbols and notations for lens dimensions and orientation used in technical documents and labelling.
• Terms related to manufacturing, packaging and basic performance descriptors.
• Vocabulary intended for harmonization across standards, regulatory documents and product information.
• Reference baseline for later consolidation into the ISO 18369 series (expanded classification and labelling guidance).

Typical use and users

Used by contact lens manufacturers, quality and regulatory affairs professionals, standards developers, test laboratories, technical writers, product labelling teams, clinicians and ophthalmic equipment suppliers who need a consistent set of terms and symbols when specifying, testing, labelling or regulating contact lens products.

Related standards

ISO 8320-1:2003 is part of a family of standards on contact lenses and optics. It was developed from earlier vocabulary standards (ISO 8320:1986 and related parts) and has been revised and consolidated into the ISO 18369 series (notably ISO 18369-1:2006 and later editions) which provide expanded vocabulary, classification and labelling recommendations. Other related documents include ISO 8320-2 and various parts of ISO 8321 and ISO 11539 that were addressed in the consolidation to ISO 18369.

FAQ

Q: What is this standard?

A: ISO 8320-1:2003 is an international standard that defines vocabulary and symbols specifically for contact lenses (Part 1: Contact lenses), intended to harmonize terms used across related standards and technical documents.

Q: What does it cover?

A: It covers definitions and terms for contact lens properties (physical, chemical and optical), common symbols for lens dimensions and descriptors used in manufacturing, testing and labelling. It provides the lexical foundation referenced by other ophthalmic standards.

Q: Who typically uses it?

A: Manufacturers, test laboratories, regulatory and quality professionals, standards committees, technical authors and clinicians who require consistent terminology for specification, testing, labelling and communication about contact lenses.

Q: Is it current or superseded?

A: ISO 8320-1:2003 has been withdrawn and its content was consolidated into the ISO 18369 series (beginning with ISO 18369-1:2006 and later revisions). Users should consult the current ISO 18369 series for the up-to-date vocabulary, classification and labelling requirements.

Q: Is it part of a series?

A: Yes. ISO 8320-1:2003 was part of a set of optics/ophthalmic vocabulary standards and was superseded by the ISO 18369 series, which covers vocabulary, classification and labelling for contact lenses and related care products.

Q: What are the key keywords?

A: Contact lenses, vocabulary, ophthalmic optics, labelling, lens materials, symbols, ISO 8320, ISO 18369.
