Zone Quick Test

Diagnosing Dry Eye with Zone Quick

The Zone Quick Test is a diagnostic tool in optometry for assessing tear volume and diagnosing dry eye conditions. This test utilizes phenol red-impregnated threads that are placed at the junction of the lower eyelid for a brief period. The threads change color in response to the tear volume, turning from yellow to red, which allows for a quantitative measure of tear production.

Benefits include:
-Quick Results: provides immediate results, making it suitable for routine screenings;
-Minimal Discomfort: non-invasive and causes minimal discomfort for the patient;
-Quantitative Measure: offers a quantitative assessment of tear production, aiding in diagnosis.
