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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

electro-optical sunglare filter
electro-optical sunglass filter
filter that varies, by electro-optical means, its luminous transmittance depending upon the illuminance
and spectral bands to which it is exposed or by manual control
Note 1 to entry: The change in luminous transmittance may be under automatic or manual control, or a
combination. For example, where the luminous transmittances in the faded and darkened states are set manually,
and transitions between them automatically. The luminous transmittance of the filter therefore varies within
certain limits in response to the illuminance.

default mode
luminous transmittance state of an electro-optical sunglare filter (3.2) when the power supply is
disconnected or malfunctions
Note 1 to entry: The power supply can be mains electricity, a battery or a photovoltaic cell.
4 Construction and materials
4.1 Construction
When tested in accordance with ISO 18526-3:2020, 6.1, areas of the sunglass, including the frame and,
if in a rimless or semi-rimless style, the edges of the filters, that may come into contact with the wearer
during intended use shall be smooth and without sharp projections.
NOTE Manufacturers are recommended to use the range of screw sizes and threads used in sunglass frames
as specified in ISO 11381.
4.2 Filter material and surface quality
When tested in accordance with ISO 18526-3:2020, 6.6, except in a marginal area 5 mm wide, sunglass
filters shall have no material or machining defects within an area of 30 mm diameter centred on the
reference point that could impair vision, e.g. bubbles, scratches, inclusions, dull spots, pitting, mould
marks, notches, reinforced areas, specks, beads, water specks, pock marks, gas inclusions, splintering,
cracks, polishing defects or undulations. If this 5 mm wide portion around the edge of the test sample
intrudes into this circular area, then this intrusion shall be excluded from testing.
4.3 Physiological compatibility
Sunglasses shall be designed, manufactured and packaged in such way that, when used under normal
conditions, they will not compromise the health or safety of the wearer. The risks posed by substances
leaking or evaporating from the sunglasses that can come into prolonged contact with the wearer shall
be reduced by the manufacturer to within the limit of any applicable regulatory requirement.
Special attention shall be given to substances that are allergenic, carcinogenic, mutagenic or toxic to
reproduction.
NOTE 1 Excessive pressure due to a poor fit on the head, chemical irritation and allergy are known to produce
reactions. Rare or idiosyncratic reactions to any material can occur and the individual wearer is well advised to
avoid those types of frame materials.
Substances recommended for cleaning, maintenance or disinfection shall be known to be unlikely to
have any adverse effect upon the wearer, when applied in accordance with the instructions given in the
information to be supplied by the manufacturer.
Manufacturers/suppliers shall perform an appropriate risk analysis on potentially harmful substances
contained in the sunglasses that, when the sunglasses are used under normal conditions, the health
(and safety) of the wearer shall not be compromised.
The following are examples of documents that represent the appropriate information:
a) specification of the material(s);
b) safety data sheets relating to the materials;
c) information relating to the suitability of the materials for use in medical devices, or other relevant
applications;
d) information relating to toxicological, allergenic, carcinogenic, toxic to reproduction, or mutagenic
investigations on the materials.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

4 Construction and materials
4.1 Construction
When tested in accordance with ISO 12311:2013, Clause 6, areas of the sunglass, including the frame
and, if in a rimless or semi-rimless style, the edges of the filters that may come into contact with the
wearer during intended use shall be smooth and without sharp projections.
NOTE Manufacturers should restrict the range of screw sizes and threads used in sunglass frames to those
specified in ISO 11381:2016 Optics and optical instruments – Ophthalmic optics – Screw threads.
4.2 Filter material and surface quality
When tested in accordance with ISO 12311:2013, 6.2, except in a marginal area 5 mm wide, sunglass
filters shall have no material or machining defects within an area of 30 mm diameter centred on the
reference point that might impair vision, e.g. bubbles, scratches, inclusions, dull spots, pitting, mould
marks, notches, reinforced areas, specks, beads, water specks, pocking, gas inclusions, splintering,
cracks, polishing defects or undulations. If a 5 mm wide portion around the edge of the test sample
intrudes into this circular area, then this intrusion shall be excluded from testing.
4.3 Physiological compatibility
Sunglasses shall be designed manufactured and packaged in such way that, when used under normal
conditions they will not compromise the health or safety of the wearer. The risks posed by substances
leaking or evaporating from the sunglasses that can come into prolonged contact with the wearer, shall
be reduced by the manufacturer to within the limit of any applicable regulatory requirement.
Special attention shall be given to substances that are allergenic, carcinogenic, mutagenic or toxic to
reproduction.
NOTE 1 Excessive pressure due to a poor fit on the head, chemical irritation and allergy are known to produce
reactions. Rare or idiosyncratic reactions to any material known to occur and the individual wearer is well
advised to avoid those types of frame materials.
Substances recommended for cleaning, maintenance or disinfection shall be known to be unlikely to
have any adverse effect upon the wearer, when applied in accordance with the instructions given in the
information to be supplied by the manufacturer.
Manufacturers/suppliers shall perform an appropriate risk analysis on potentially harmful substances
contained in the sunglasses that, when the sunglasses are used under normal conditions, the health
(and safety) of the wearer shall not be compromised.
The following are examples of documents that represent the appropriate information.
a) Specification of the material(s)
b) Safety data sheets relating to the materials
c) Information relating to the suitability of the materials for use with food, in medical devices, or
other relevant applications
d) Information relating to toxicological, allergenic, carcinogenic, toxic to reproduction, or mutagenic
investigations on the materials.
NOTE 2 Attention is drawn to specific national regulations that restrict chemical substances, e.g. ISO 12870,
4.2.3 for nickel release test methods and requirements.

4.4 Headforms
Unless the manufacturer specifies the headform(s) in accordance with ISO 18526-4:2020 that is/are
compatible with the sunglasses, the test methods where (a) headform(s) is/are required shall use the
headform 1-M in accordance with ISO 18526-4:2020 as the default.
5 Transmittance
5.1 Test methods
Transmittance values shall be determined in accordance with ISO 12311:2013, Clause 7. If the direction
of measurement is not specified, then it shall be measured normal to the surface of the test sample at
the geometrical centre.
5.2 Transmittance and filter categories
Sunglass filters for general use shall be assigned to one of five filter categories based on the luminous
transmittance at their reference point.
The range of the luminous transmittance of these five categories is given by the values in Table 1. An
overlap of the transmittance values shall be not more than ± 2 % (absolute) between adjacent categories
0, 1, 2 and 3. There is no overlap in transmittance values between categories 3 and 4.
The maximum deviation for the declared luminous transmittance value shall be ± 3 % absolute for
the transmittance values falling in categories 0 to 3 and ± 30 % relative to the stated value for the
transmittance values falling in category 4.
For gradient-tinted and/or mirrored filters, the maximum deviation for the declared luminous
transmittance value shall be double that for uniformly tinted lenses.
When describing the transmittance properties of photochromic filters, two categories for transmittance
values are generally used. These two values correspond to the faded state and to the darkened state of
the filter.
In the case of gradient-tinted filters, the transmittance value at the reference point shall be used to
characterize the luminous transmittance and the category of the filter.
For gradient-tinted filters, the overlap in luminous transmittance allowed between categories shall be
double that for uniformly tinted filters.
Table 1 also specifies the UV requirements for sunglass filters for general use and, when the filters are
claimed by the manufacturer to protect against IR radiation, the IR requirements.

Only applicable to sunglass filters recommended by the manufacturer as a protection against infrared radiation.
5.3 General transmittance requirements
5.3.1 Uniformity of luminous transmittance
The relative difference in the luminous transmittance value between any two points of the filter within
a circle 30 mm in diameter centred on the reference point shall not be greater than 15 % (relative to
the higher value), except for category 4 where it shall not be greater than 20 %. If a 5 mm wide portion
around the edge of the test sample intrudes into this circular area, then this intrusion shall be excluded
from testing
The geometric or boxed centre takes the place of the reference point if this is not known.
In the case of mounted gradient filters, this requirement shall be limited to sections parallel to the line
connecting the two reference points.
For mounted filters, the relative difference between the luminous transmittance value of the filters at
the reference point for the right and left eyes shall not exceed 20 % for gradient-tinted filters and 15%
for all other types (relative to the lighter filter).
Changes of luminous transmittance that are caused by thickness variations due to the design of the
filter are permitted. For verification, the test method in ISO 12311:2013, Annex L shall be used.
