Ophthalmic optics - Contact lenses - Part 3 : measurement methods

ISO 18369-3:2006 specifies the methods for measuring the physical and optical properties of contact lenses specified in ISO 18369-2, i.e. radius of curvature, back vertex power, diameter, thickness, inspection of edges, inclusions and surface imperfections, and determination of spectral and luminous transmittances. ISO 18369-3:2006 also specifies the equilibrating solution, standard saline solution, for testing of contact lenses.

Ophthalmic optics - Contact lenses - Part 3 : measurement methods

ISO 18369-3:2017 specifies the methods for measuring the physical and optical properties of contact lenses specified in ISO 18369‑2, i.e. radius of curvature, label back vertex power, diameter, thickness, inspection of edges, inclusions and surface imperfections and determination of spectral transmittance. This document also specifies the equilibrating solution and standard saline solution for testing of contact lenses.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
