ISO 12312-3:2022

Eye and face protection - Sunglasses and related eyewear - Part 3: Sunglasses for running, cycling and similar active lifestyles

This document is applicable to all nominally afocal (plano power) sunglasses for protection against environmental elements, such as solar radiation, wind, dust and rain when running, cycling and following similar active lifestyle recreational activities but not intended for competitive sporting activities where enhanced impact resistance is required. The document specifies additional material, design, performance and marking requirements. The other applicable requirements are given in ISO 12312‑1. This type of sunglass is designed to reduce secondary hazards to the wearer in an accident rather than to provide high amounts of impact protection which may be difficult in a spectacle format. This document is not applicable to: a) eyewear for protection against radiation from artificial light sources, such as those used in solaria; b) eye protectors intended for specific sports, e.g. ski goggles or other types – see ISO18527 (all parts); c) eye protectors for sports that include the use of a ball, stick, bat, racquet or other implement; d) sunglasses that have been medically prescribed for attenuating solar radiation; e) products intended for direct observation of the sun, such as for viewing a partial or annular solar eclipse, for which ISO12312-2 applies; f) products intended for occupational eye protection – for example, see ISO16321 (all parts).

Overview

ISO 12312-3:2022 - “Eye and face protection - Sunglasses and related eyewear - Part 3” defines material, design, performance and marking requirements for sunglasses for running, cycling and similar active lifestyles. It applies to nominally afocal (plano power) sunglasses intended to protect wearers from environmental elements (solar radiation, wind, dust, rain) during recreational active use - but excludes competitive sports requiring enhanced impact protection, occupational eye protection, medically prescribed filters, and products for direct solar observation.

Keywords: ISO 12312-3, sunglasses for running, cycling eyewear, active lifestyle sunglasses, sunglass standards.

Key topics

• Scope & exclusions: Recreational active-use sunglasses only; not for occupational, medical, competitive-impact sports or solar observation (see ISO 12312‑2).
• Reference requirements: Incorporates general requirements from ISO 12312‑1:2022 (construction, transmittance, refractive power, solar radiation resistance, ignition resistance).
• Robustness & mechanical strength:
  • Frame deformation, filter retention and resistance to perspiration are mandatory.
  • Increased endurance and strength level 2 robustness are required (tests per ISO 18526‑3).
  • Strength level 3 (impact resistance of the filter) is optional; if claimed, tested per ISO 18526‑3.
• Optical and protective requirements:
  • Transmittance and refractive power as per ISO 12312‑1.
  • Field-of-view and coverage ellipses defined for adult and children headforms (specific dimensions provided).
• Optional features:
  • Abrasion resistance and fog-resistance (fog test: filter alone must not fog in less than 30 s under ISO 18526‑3 conditions).
• Marking and user information:
  • Mandatory labelling (model ID, manufacturer, reference to ISO 12312‑3:2022, filter type/category, symbols).
  • Special marks: letter “A” for active lifestyle; letter “N” for fog resistance; driving suitability warnings and required wording/symbol sizes.
• Test sampling & conditioning: Random sampling, conditioning 4 h at 23 °C ±5 °C; minimum sample counts specified (e.g., at least 4, or 6 for nickel release testing).

Applications

• Guidance for sunglass manufacturers designing durable lenses and frames for running, cycling and outdoor recreation.
• Reference for testing laboratories performing mechanical, optical and environmental tests.
• Use by retailers, product certifiers, specifiers and regulators to verify labeling, warnings and suitability for active lifestyle consumers.
• Helpful to product designers seeking to balance comfort, coverage and secondary-hazard reduction (rather than full high-impact protection).

Related standards

• ISO 12312‑1:2022 - Sunglasses for general use
• ISO 12312‑2 - Filters for direct solar observation
• ISO 18526‑3:2020 - Test methods (physical/mechanical)
• ISO 18527 (all parts) - Sport-specific eyewear (e.g., ski goggles)
• ISO 16321 (all parts) - Occupational eye protection
• ISO 4007 - Eye and face protection vocabulary

ISO 12312‑3:2022 is essential for stakeholders producing or assessing active lifestyle sunglasses to ensure safety, durability and correct consumer information.

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
