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.
