Schirmer's test - Overview

Alternative Names

Tear test; Tearing test; Dry eye test

Definition of Schirmer's test:

Schirmer's test determines whether the eye produces enough tears to keep it moist.

How the test is performed:

The health care provider will place paper strips under the eyelid, usually the bottom one. Both eyes are tested at the same time. Before the test, you may be given numbing eye drops to prevent your eyes from tearing due to irritation from the paper.

The exact procedure may vary somewhat. Most often, the eyes are closed for about 5 minutes. Close the eyes gently. Tight closing of the eyes or rubbing the eyes during the test can cause abnormal test results.

After 5 minutes, the doctor removes the paper and measures how moist it is.

How to prepare for the test:

Remove contact lenses before the test.

How the test will feel:

Some people find that holding the paper against the eye is irritating or mildly uncomfortable.

Why the test is performed:

This test is used when a person experiences very dry eyes or excessive watering of the eyes.
