Ophthalmic optics - Visual acuity testing - Standard optotype and its presentation (ISO 8596:2009)
This International Standard 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. For the purposes of measuring visual acuity, the standard optotype should be used. For clinical use, see the recommendation prepared by the Visual Functions Committee of the International Council of Ophthalmology.
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)
L'ISO 8596:2009 spécifie une gamme d'optotypes constitués d'anneaux de Landolt et décrit une méthode de mesure de l'acuité visuelle en vision de loin, en condition diurne, à des fins de délivrance d'attestations ou de permis.
Elle ne s'applique ni aux mesurages d'acuité visuelle pratiqués au cours des examens cliniques ni à ceux effectués en vue d'un certificat pour cécité ou baisse de la vue.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 8596 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 7,
Ophthalmic optics and instruments.
This second edition cancels and replaces the first edition (ISO 8596:1994), which has undergone minor
revision to take into account the withdrawal without replacement of ISO 8597:1994, Optics and optical
instruments — Visual acuity testing — Method of correlating optotypes.
