Schirmer's Tear Test Strips with Blue Mark
Individually wrapped diagnostic ophthalmic sterile strips. Gauged for easy reading, to help measure the amount of tear production.
As there are slight variations in different STT strips, we recommend that the same test strip be used consistently on a patient to ensure accurate monitoring.

Directions for Use:
Do not apply any topical medication to the eye or perform any manipulation of the eye before performing this test. Examination room lights should be dimmed. Carefully open strips according to directions. While patient looks up, insert the rounded end into the lower temporal lid margin of the eye, making sure the strip fits snugly. Wait for 5 minutes, remove the strip and record the length of the moistened area indicated by the distance travelled by the blue indicator dye.
