eye irritation tests

Eye irritation tests evaluate how substances affect the eyes, helping ensure safety before use in products like cosmetics or pharmaceuticals. Typically, a small amount of the substance is applied to the eye area or directly to the eye of a test subject (often animals or, increasingly, in vitro models). Researchers observe any signs of redness, swelling, tearing, or discomfort over time. These tests help determine if a substance is irritating or harmful, guiding decisions on product safety and labeling. The goal is to minimize pain and ensure products do not cause adverse eye reactions in consumers.
