The eponymic Schirmer tear test strip is currently supplied as a strip of 5 mm x 35 mm Whatman no. Schirmer Tear Tests are easy-to-read, calibrated test strips used to measure the volume of tear production in an animal. Low tear production can contribute to a number of eye problems. Strips are marked for left and right eye. This diagnostic strip made from Whatman filter paper no 41 measures the amount of tear production.
