Dynamics of an Artificial Tear Film on Contact Lenses in Response to a Moving Force Mimicking Fingertip Application

Globally, it is estimated that more than 140 million people wear contact lenses. As a result, users demonstrate varying levels of dexterity and consistency when inserting lenses, often requiring fine adjustments. Moreover, the diverse structure and quality of individuals' precorneal tear films lead to different tear film responses under various insertion conditions. In this work, we mimic such tear film dynamics using a force probe coupled with …
