A dry eye test is used to measure the quality and quantity of your tears to determine if you have dry eye syndrome. Common tests include the Schirmer’s test, which measures tear production, and the tear breakup time (TBUT) test, which evaluates how quickly tears evaporate from the eye's surface.
These tests help eye doctors understand whether your eyes produce enough tears or if the tears evaporate too quickly, guiding the best treatment plan to relieve discomfort and protect eye health.
