Personal eye-equipment - Sunglasses and sunglare filters for general use and filters for direct observation of the sun
This European Standard specifies physical properties (mechanical, optical etc.) for sunglasses and sunglare filters of nominal plano power which are not prescription lenses, intended for protection against solar radiation for general use, for social and domestic purposes, including road use and driving. This European Standard specifies also requirements for filters for the direct observation of the sun (e.g. during eclipses). Guidance for selection and use of these filters is given in Annex E. For sunglasses and sunglare filters for industrial use, EN 166 and EN 172 apply.
This European Standard does not apply to eyewear for protection against radiation from artificial light sources, such as those used in solaria. EN 170 applies for these filters.
This European Standard does not apply to ski goggles, for which EN 174 applies, or other types of eye protection used for leisure activities.
This European Standard does not apply to sunglasses and filters that have been medically prescribed for attenuating solar radiation.
Persönlicher Augenschutz - Sonnenbrillen und Sonnenschutzfilter für den allgemeinen Gebrauch und Filter für die direkte Beobachtung der Sonne
Dieses Dokument legt die physikalischen Eigenschaften (mechanische, optische usw.) von Sonnenbrillen und Sonnenschutzfiltern mit Nennbereich Null fest, die keine Korrektionsbrillengläser sind, welche zum Schutz gegen Sonnenstrahlung für den allgemeinen Gebrauch, den gesellschaftlichen sowie privaten Bereich, einschließlich Autofahren und Straßenverkehr vorgesehen sind. Außerdem legt dieses Dokument Anforderungen an Filter für die direkte Betrachtung der Sonne (z. B. während einer Sonnenfinsternis) fest. Ein Leitfaden für die Auswahl und Benutzung dieser Filter ist in Anhang E angegeben. Für Sonnenbrillen und Sonnenschutzfilter für den gewerblichen Gebrauch gelten EN 166 und EN 172.
Das vorliegende Dokument gilt nicht für den Schutz des Auges gegen die Strahlung künstlicher Lichtquellen, z. B. von Solarien. Diese Filter müssen EN 170 entsprechen.
Dieses Dokument gilt weder für Skibrillen, für die EN 174 gilt, noch für andere Augenschutzgeräte für Freizeitaktivitäten.
Ferner gilt dieses Dokument nicht für Sonnenbrillen und Filter, die aus medizinischen Gründen zur Dämpfung von Sonnenstrahlung verschrieben werden.

L'Annexe E constitue un guide de sélection et d'utilisation de ces filtres. L'EN 166 et l'EN 172 sont applicables aux lunettes et aux filtres de protection contre les rayonnements solaires pour l'usage industriel.
La présente Norme européenne n'est pas applicable aux équipements de protection de l'oeil contre les rayonnements des sources de lumière artificielle, tels que ceux des solariums. L'EN 170 s'applique à ce type de filtres.
La présente Norme européenne n'est pas applicable aux masques pour le ski, pour lesquels l’EN 174 s’applique, ni aux autres types d'équipements de protection de l'oeil utilisés dans le cadre d'activités de loisirs.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 165:1995 and IEC 60050-
845:1987 and the following apply.
3.1
absorptance (absorption)
absorptance is the difference 1 minus transmittance minus reflectance
NOTE Some manufacturers use the term absorption and specify the value of the absorption as the difference 1
minus the luminous transmittance.
3.2
degree of polarisation, P
defined as:
τ −τ
pmax pmin
P =
τ +τ
pmax pmin
where
τ is the maximum values of luminous transmittance as determined with linearly polarised radiation;
pmax
τ is the minimum values of luminous transmittance as determined with linearly polarised radiation.
pmin
3.3
luminous transmittance of photochromic sunglare filters
five different values of the luminous transmittance of photochromic sunglare filters are defined by this
European Standard:
τ luminous transmittance in the faded state as reached at 23 °C after specified
conditioning;
luminous transmittance in the darkened state as reached at 23 °C after specified
τ
irradiation simulating mean outdoor conditions;
luminous transmittance in the darkened state as reached at 5 °C after specified
τ
w
irradiation simulating outdoor conditions at low temperatures;
τ luminous transmittance in the darkened state as reached at 35 °C after specified
s
irradiation simulating outdoor conditions at high temperatures;
luminous transmittance in the darkened state as reached at 23 °C after specified
τ
a
irradiation simulating reduced light conditions.
3.4
photochromic range, R
p
range given by the ratio of the difference of the luminous transmittance in the faded state τ and the luminous
transmittance in the darkened state τ to the luminous transmittance in the faded state τ :
τ − τ
0 1
R =
p
