ISO 12609-1:2021

Overview

ISO 12609-1:2021 specifies product requirements for eye and face protection against intense light sources (ILS) used on humans and animals for cosmetic and medical applications. It covers operators’ and patient protectors (except for periorbital treatments) against excessive optical radiation in the spectral range 250 nm to 3 000 nm - excluding laser radiation. The standard defines classes of ILS eye protectors, general design and safety requirements, and test-related properties to ensure reliable protection during procedures such as IPL, phototherapy and other non‑laser light treatments.

Key Topics and Technical Requirements

• Scope and limits
  • Applies to non‑laser ILS equipment for cosmetic and medical use; does not apply to laser protectors, tanning equipment, solar sunglasses, or ionizing radiation protectors.
  • Intended for normal ambient temperatures: (23 ± 5) °C.
• Classes
  • F‑scale: scale number based on luminous transmittance (CIE D65).
  • B‑scale: scale number based on blue‑light transmittance.
  • Opaque protectors: for patient use only (spectral transmittance ≤ 0.01% across 250–3 000 nm).
• Optical performance
  • Requirements for spectral and luminous transmittance, uniformity, colour neutrality (optional) and angular dependence.
  • Specific guidance for autodarkening filters: transmittance, angular behavior and switching time.
• Physical and mechanical properties
  • Construction, fit and physiological compatibility (materials, allergenic/toxic risks).
  • Frame design, lateral protection, field of view, optical power, prism imbalance and narrow‑angle scatter.
  • Resistance to UV, thermal exposure, ignition and basic impact level testing.
• Usability and information
  • Cleaning/disinfection instructions, headform compatibility for testing, mandatory markings and manufacturer information to be supplied.

Applications

ISO 12609-1 is used to design, test and certify protective eyewear for procedures involving intense non‑laser light, including:

• IPL hair removal, photorejuvenation and vascular or pigment treatments in cosmetic clinics
• Dermatology and phototherapy treatments in healthcare settings
• Veterinary light‑based procedures
• Manufacturing and quality control of operator and patient eye protectors

Who should use this standard

• Protective eyewear manufacturers - product design, compliance and labeling
• Medical device developers - integration of safe ILS workflows
• Clinicians and estheticians - selection and safe use of operator/patient protectors
• Testing laboratories and conformity assessors - verification against optical and mechanical requirements
• Procurement and regulatory teams - specification of compliant eye protection for clinics and salons
