Full title and description

ISO 10344:1996 — Optics and optical instruments — Contact lenses — Saline solution for contact lens testing. This short International Standard (originally published in 1996) defines a standardized saline solution intended for use in laboratory testing and equilibration of contact lenses and contact‑lens materials; historically available in PDF format as a 3‑page document.

Abstract

Specifies a saline solution for use when conducting standardized tests to determine dimensions, physical, chemical and biological characteristics of contact lenses and contact lens materials. The solution is not intended for the purpose of packaging finished contact lenses.

Scope

Applies to a defined saline (balanced salt) solution used to equilibrate contact lenses or lens materials prior to testing and to immerse lenses during specific laboratory test procedures for dimensional, physical, chemical and biological characterization. It explicitly excludes use of the solution as a packaging or storage solution for finished contact lenses.

Key topics and requirements

• Composition and concentration: specifies the salts and concentrations that make up the standard saline used for test immersion and equilibration.
• Preparation and labelling: instructions for preparing the solution under controlled conditions and handling to avoid contamination.
• Intended uses: equilibration of lenses or lens materials before measurement and immersion during test procedures (dimensional, physical, chemical and biological tests).
• Limitations: not intended for packaging finished contact lenses and not to be treated as a commercial lens‑care product.
• Compatibility notes: used as the reference medium for instruments and test methods that require lenses to be measured in solution; where appropriate, test methods reference the standard saline solution.

Key requirements and intended uses are described in the ISO 10344 text; later consolidated/updated test requirements appear in the ISO 18369 series that superseded this document.

Typical use and users

Laboratories performing standardized contact‑lens testing, ophthalmic‑instrument calibration groups, contact‑lens manufacturers and R&D teams, standards developers, and regulatory reviewers use the saline solution defined by this standard to ensure repeatable test environments for measuring dimensions, water content, optical and biological properties of lenses and lens materials.

Related standards

ISO 10344:1996 has been withdrawn and its subject matter was incorporated in the broader ISO 18369 series (Ophthalmic optics — Contact lenses), notably ISO 18369‑3 (and later revisions). Related test standards in the contact‑lens family include methods for thickness, refractive index, water content and back‑vertex power; national and European adoptions (EN ISO 10344, equivalents) historically mirror this content.

FAQ

Q: What is this standard?

A: ISO 10344:1996 is an International Standard that defined a standardized saline solution for use in the laboratory testing and equilibration of contact lenses and contact‑lens materials.

Q: What does it cover?

A: It covers the composition, preparation and intended laboratory use of a saline (balanced salt) solution for specific standardized tests of contact lenses (dimensional, physical, chemical and biological testing) and states that the solution is not intended for packaging finished lenses.

Q: Who typically uses it?

A: Test laboratories, contact‑lens manufacturers (R&D and QC), instrument calibration teams, standards bodies and regulators who need a consistent immersion/equilibration medium for reproducible test results.

Q: Is it current or superseded?

A: ISO 10344:1996 has been withdrawn. Its content was incorporated into the ISO 18369 series (Ophthalmic optics — Contact lenses), specifically ISO 18369‑3 (and later revisions), which should be consulted for the current, consolidated requirements.

Q: Is it part of a series?

A: Yes — the subject matter is now part of the ISO 18369 series (Ophthalmic optics — Contact lenses), which groups test methods, definitions and requirements for contact lenses and related materials.

Q: What are the key keywords?

A: Contact lens saline, test saline, equilibration solution, ophthalmic optics, ISO 10344, ISO 18369.
