OptiSafe™ Eye Irritation Test
The only OECD TG 496-validated, fully nonanimal eye irritation test with patented human tear chemistry. Zero false negatives. Results in under 24 hours.
About the OptiSafe™ EIT
The OptiSafe™ Eye Irritation Test (OS EIT) macromolecular test matrix is composed of plant-derived proteins, lipids, and nucleotides — no animal ingredient or component of any kind. The method measures the extent of damage to the macromolecular matrix upon exposure to a test chemical, and the measured extent of macromolecular damage is used to predict the toxicity of the tested chemical to the eye.
- Validated with international regulatory acceptance (OECD Test Guideline 496)
- True nonanimal eye irritation test — no animal component of any kind
- Rapid turnaround: quantitative results in less than 24 hours
- 100% sensitivity — no false negatives for non-irritant vs. rest discrimination
- Patented tear chemistry reduces false positive rate to lowest of any nonanimal test
