Gently touch the strip to the superior temporal bulbar conjunctiva for one or two seconds. 4. Ask the patient to blink three times and open eyes naturally. 5. Conduct the FBUT measurements immediately. 6. Perform two consecutive measurements. If not consistent, conduct a third and average the results. 7. Repeat steps 1 through 6 using a new strip for the second eye FBUT values of less than 10 seconds are considered abnormal. Values less than 5 seconds are indicative of dry eye disorder.
