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.
