Contact Lens Care Product Labeling: Warnings, Instructions and Readability Requirements
This guidance is an addendum focusing on strengthening warnings and directions for use labeling of contact lens care products, including solutions, lens cases, and accessories. It applies to both rigid gas permeable and soft (hydrophilic) contact lens care products classified as Class II devices.
Recommended Actions
- Review and update product labeling to include enhanced warnings and instructions
- Implement “rub and rinse” directions and remove “no-rub” claims
- Add specific warnings about solution reuse, water exposure, and lens case care
- Format warnings and instructions to improve readability
- Include discard date information on product packaging
- Ensure labeling meets eighth grade reading comprehension level
- Consider adding visual aids (like infection photos) with appropriate context
- Update website content to include patient labeling information
- Develop communication strategy for eye care professionals about labeling updates
- Ensure all labeling claims are supported by pre-clinical testing data
Key Considerations
Non-clinical testing
- Pre-clinical microbiology testing should support the labeled rubbing and rinsing times
Human Factors
- Patient information labeling should not exceed eighth grade reading comprehension level
- Labeling should be easily readable and formatted to enhance readability
- Consider reasonable rinse times that promote user compliance
Labelling
- Include a glossary after table of contents
- Remove “no-rub” from product labeling and emphasize “rubbing and rinsing”
- Include specific warnings for:
- Solution reuse/”topping off”
- Water exposure
- Lens case care
- Discard dates
- Include instructions for bringing lenses, solutions, and case to eye care provider if infection occurs
- Multi-purpose products should only be labeled for cleaning, disinfecting, storing and rinsing
- Include fill-in space for “date opened or discard date” on bottle label
Safety
- Emphasize risks and complications associated with improper use
- Include specific warnings about water exposure and contamination risks
- Provide clear instructions for lens case cleaning and replacement
Other considerations
- Consider placing patient labeling on manufacturer’s website
- Recommend eye care professionals review labeling with patients
