Measurement of the Surface Tension of Tears

Measurement of the Surface Tension of Tears Abstract The average surface tension of the tears of six human subjects was found to be two-thirds that of water. The experimental method involved the use of a scleral contact lens which contained a circular tear collecting trough. Surface tension measurements using a fine wire ring were carried out while the contact lens rested on the subject's eyes. References 1.

Abstract

Abstract The average surface tension of the tears of six human subjects was found to be two-thirds that of water. The experimental method involved the use of a scleral contact lens which contained a circular tear collecting trough. Surface tension measurements using a fine wire ring were carried out while the contact lens rested on the subject's eyes. References 1.
