Do Schirmer Tear Test Strips (PO-6394) include printed measurement lines?

Schirmer Tear Test Strips (PO-6394) do not feature printed gradation lines; instead, each sterile strip has a pre-marked notch that serves as the reference point. After the 5-minute test, measure the length of moisture migration past the notch against a millimeter ruler or the guide printed on the packaging.

If you need printed measurement lines directly on the strip, consider Amcon Tear Flow Test Strips, which include a built-in metric scale for millimeter-accurate readings:

• Printed metric scale on each sterile, lint-free strip
• Comfortable rounded tip for precise, painless application
• Box of 100 individually wrapped strips for hygienic testing
• Made in the USA for consistent quality and reliability
