Disposable Schirmer Tear Test Strip Pack Of 100 Pieces

The tear test strip you mentioned, known as a Schirmer test strip, is another diagnostic tool used in ophthalmology to assess tear production. Unlike the Rose Bengal test, which evaluates the quality of tears and the health of the ocular surface, the Schirmer test measures the quantity of tears produced by the lacrimal gland.

During a Schirmer test, the strip is inserted into the lower eyelid of the patient's eye, typically after applying a local anesthetic to reduce discomfort. The strip is left in place for a specified period, often around 5 minutes, allowing tears to be absorbed by the strip. After removal, the length of wetting on the strip is measured, indicating the amount of tear production.
