The Effect of the Addition of Electrolyte Solutions on the Ferning Patterns of Tears Collected from Normal Eye Subjects.

Significance: The current study is the first report to describe the improvement of ferning patterns of human tears using electrolyte solutions. The results can help in the production of new artificial tears to improve the quality of tears.

Purpose: This study aimed to investigate the effect of the addition of different volumes of various electrolyte solutions on ferning patterns of human tears.
