Scope

This part of ISO 9339 describes a method for the determination of thickness of soft (hydrogel) contact lenses by means of a low-force gauge. NOTE 1 This method is suitable for comparison of thickness between contact lenses, but may not be indicative of the absolute thickness of a contact lens. NOTE 2 ISO 9339-1 is applicable for the determination of thickness of rigid contact lenses.
