TS EN ISO 8320-1

TS EN ISO 8320-1 is the first part of the vocabulary series for contact lenses and contact lens care products, focused specifically on contact lenses. It supports the consistent use of terminology across manufacturing, clinical practice, technical documentation, and communication by defining the subject area in a shared technical language. This record represents a withdrawn edition; the description below provides general technical background based on the title, not a clause-by-clause reading of the full standard.

Why contact lens terminology matters

Contact lenses are optical medical devices placed on the cornea to correct vision, serve cosmetic purposes, or meet specialised clinical needs. In this field, terminology is essential for distinguishing between hard and soft lenses, daily disposable and planned replacement lenses, toric or multifocal designs, and other product categories. Vocabulary standards help ensure these distinctions are expressed consistently so manufacturers, eye-care professionals, laboratories, and users are referring to the same concepts.

What this part contributes

The designation “Part 1: Contact lenses” indicates that this part is about the lenses themselves rather than care solutions or accessories. In general technical context, vocabulary work of this kind supports a common understanding of lens geometry, material behaviour, wearing schedules, and clinical classification. However, the official scope text is not available for this record, so no specific mandatory definitions, exclusions, or classification rules should be attributed to this edition here.
