Ophthalmic optics - Contact lenses - Part 3: Measurement methods (ISO 18369-3:2006)

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.

Augenoptik - Kontaktlinsen - Teil 3: Messverfahren (ISO 18369-3:2006)

Dieser Teil von ISO 18369 legt die Verfahren fest, die zur Messung der in ISO 18369-2 festgelegten mechani¬schen und optischen Eigenschaften von Kontaktlinsen erforderlich sind. Im Einzelnen handelt es sich um die Messung des Krümmungsradius, des bildseitigen Scheitelbrechwertes, des Durchmessers und der Dicke, die Beurteilung der Ränder, die Beurteilung von Einschlüssen und Oberflächenfehlern sowie die Bestimmung des spektralen Transmissionsgrades und des Lichttransmissionsgrades. Dieser Teil von ISO 18369 legt weiterhin die zur Verwendung bei der Prüfung von Kontaktlinsen erforderliche Äquilibrierungslösung (Kochsalzlösung) fest.

Optique ophtalmique - Lentilles de contact - Partie 3: Méthodes de mesure (ISO 18369-3:2006)

L'ISO 18369-3:2006 spécifie les méthodes de mesure des propriétés optiques et physiques des lentilles de contact, telles que décrites dans l'ISO 18369-2, il s'agit en l'occurrence du rayon de courbure, de la puissance frontale postérieure, du diamètre, de l'épaisseur, du contrôle des bords, des inclusions et des imperfections de surface et de la détermination du facteur spectral de transmission et du facteur de transmission et, pour finir, elle spécifie la solution saline étalon pour l'essai des lentilles de contact.
