How do toxicological assessments evaluate the impact on the tear film?
Toxicological assessments utilize various techniques to evaluate the impact of substances on the tear film. These include Schirmer test for tear production, tear breakup time (TBUT) for stability, and lipid layer thickness measurements. Additionally, biomarkers in the tear fluid can be analyzed to detect inflammatory responses or oxidative stress induced by toxicants. Such assessments provide valuable insights into the safety and efficacy of chemical products and environmental standards.
