At CLAIM, the team has developed an innovative, quantitative, and non-invasive method to assess the occular tolerance of cosmetic products by evaluating tear film stability. Unlike traditional approaches, this protocol combines clinical expertise with advanced diagnostic technology to objectively measure a product’s impact on the eye. Specialized ophtalmological equipment is employed, including a slit lamp, image recording systems, and NIBUT (Non-Invasive Break-Up Time) technology, which projects Placido rings onto the cornea to accurately detect tear film break-up without dyes or direct contact.
In addition, lipid layer thickness and uniformity are analyzed, together with fluorescein instillation to observe potential corneal or conjunctival damage. This approach enables robust, scientifically backed claims such as “occular-friendly”, “tear-proof”, or “non-irritating to the eye”. Fully compliant with international safety standards and animal testing bans, the methodology provides cosmetic company with accurate, reproducible, and objective data to confidently support the “ophtalmologically testes” label.
