TS 7010-1 EN ISO 8320-1

TS 7010-1 EN ISO 8320-1 is a vocabulary standard for contact lenses. It brings together the terms and definitions used for contact lenses, covering their physical, chemical and optical properties as well as their manufacture and use. In practical terms, it standardises the language used to describe how contact lenses are designed, characterised and discussed across the field.

What this vocabulary standard organises

Contact lenses are optical devices placed on or very near the corneal surface. In technical work, precise terminology is important because lens material, curvature, thickness, refractive power, water content, permeability and surface characteristics are distinct concepts with different implications. General technical context: these distinctions support consistent communication in design, production, inspection, clinical practice and product description.

The scope of this document is the identification and definition of terms, not the specification of lens requirements or a test method. Its role is to provide a common technical vocabulary for properties and processes associated with contact lenses, helping manufacturers, laboratories, clinicians and users refer to the same concepts in the same way.

Why shared terminology matters

• To distinguish optical performance from material and surface characteristics
• To separate manufacturing language from clinical and usage-related language
• To reduce ambiguity in product documentation and technical communication
• To align the vocabulary used for contact lenses with the broader field of eye care technology
