IS 19517 (Part 1) : 2026 / ISO 12312-1 : 2022

Eye and Face Protection — Sunglasses and Related Eyewear Part 1 Sunglasses for General Use

This Indian Standard specifies the requirements for sunglasses and related eyewear intended for general use, providing a structured framework to ensure effective protection of the eyes against solar radiation. Harmonized with ISO 12312-1:2022, it aligns national requirements with internationally accepted safety and performance criteria. It applies to afocal (plano power) sunglasses and clip-ons, including those used for road use and driving, while excluding specialized eyewear designed for medical purposes, occupational protection, or direct observation of the sun.

It outlines comprehensive provisions relating to design and performance, including construction, materials, and optical characteristics. Key parameters such as luminous transmittance, refractive power, and filter categories are defined to ensure appropriate levels of glare reduction and visual clarity. The standard also specifies requirements for different usage conditions, including suitability for driving and protection in environments with varying levels of sunlight intensity.

This further prescribes detailed test methods and performance criteria to verify product reliability and safety. These include assessments of robustness, impact resistance, resistance to solar radiation, ignition, and abrasion. It also ensures uniformity of optical properties and limits visual distortions, thereby enhancing user safety and comfort during prolonged use.

In addition, this emphasizes user well-being by addressing physiological compatibility, minimizing risks from harmful materials, and ensuring proper fit and durability. It provides requirements for marking, labelling, and user information, including guidance on usage and performance claims such as UV and infrared protection. Overall, it establishes a robust framework for ensuring the quality, safety, and reliability of sunglasses across diverse conditions.
