Compliance overview
Scope and applicability
This standard specifies the requirements, labeling, and testing methods for soft contact lenses. It is mandatory for all manufacturers producing soft contact lenses intended for the Chinese market. The standard applies to various types of soft contact lenses, including those with special optical designs or UV absorption features, but excludes rigid contact lenses which are covered under GB 11417.2.
Technical requirements
The standard outlines comprehensive technical requirements across several critical categories. For optical performance, it specifies tolerances for back vertex power, cylinder power, prism, and light transmission properties, including visible light transmittance and UV absorption categories. Manufacturers must ensure strict adherence to these optical tolerances to guarantee product safety. Regarding geometric dimensions, the standard sets limits for base curve radius, total diameter, center thickness, and optic zone diameter. It also details requirements for contact lens materials, encompassing physical properties like refractive index, oxygen permeability, and water content, as well as chemical properties such as extraction limits and preservative uptake/release, referencing GB/T 28539. Furthermore, the standard mandates rigorous biocompatibility evaluation and microbial requirements. Soft contact lenses must be supplied in sterile packaging with a Sterility Assurance Level (SAL) not exceeding 10^-6. Stability testing, including radiation aging, and assessments for intrinsic quality and surface defects are also strictly specified.
Testing methods
Testing methods are primarily referenced in Appendix A of the standard, which lists applicable documents such as GB/T 11417.5 for optical performance, GB/T 11417.6 for mechanical properties, and GB/T 11417.7 for physicochemical properties. Manufacturers must use these specified test methods or provide alternative methods that simulate actual human eye application with sufficient repeatability and reproducibility. Biological evaluation tests are conducted in accordance with GB/T 16886.1.
FAQs
What products are regulated under GB 11417.3-2025?
GB 11417.3-2025 regulates soft contact lenses, including those with special medical purposes, colored lenses, and UV-absorbing lenses. It does not apply to rigid contact lenses.
Are there any updates from the previous version of GB 11417.3?
Yes, GB 11417.3-2025 replaces GB 11417.3-2012. Key changes include updates to terms, optical performance, geometric dimensions, material requirements, and the deletion of inspection rules.
How does GB 11417.3-2025 relate to ISO standards?
The standard references ISO 14534 and ISO 18369 during its revision. However, it forms a systematic national standard framework specific to the Chinese market, working in conjunction with other parts of the GB 11417 series.
The summary above provides a high-level overview of GB 11417.3-2025.
