Ophthalmic optics - Visual acuity testing - Standard optotype and its presentation (ISO 8596:2009)

ISO 8596:2009 specifies a range of Landolt ring optotypes and describes a method for measuring distance visual acuity under daylight conditions for the purposes of certification or licensing.
It is neither intended as a standard for clinical measurements nor for the certification of blindness or partial sight.

Augenoptik - Sehschärfeprüfung - Das Normsehzeichen und seine Darbietung (ISO 8596:2009)

Diese Internationale Norm legt eine Reihe von Landoltring-Sehzeichen fest und beschreibt ein Verfahren zur
Messung der Sehschärfe für die Ferne unter Tageslichtbedingungen für gutachterliche Zwecke und
Zulassungsverfahren.
Diese Norm ist weder als Norm für klinische Messungen noch zur Bestätigung von Blindheit oder Sehbehinderung
vorgesehen.
Zum Zwecke der Messung der Sehschärfe sollte das Normsehzeichen benutzt werden.
Für den praktischen Gebrauch wird auf die Empfehlungen des Visual Functions Committee des International
Council of Ophthalmology [1] verwiesen.

Optique ophtalmique - Essai d'acuité visuelle - Optotype normalisé et sa présentation (ISO 8596:2009)
