Evaluating the initial and end-of-day wettability of contemporary daily disposable contact lenses using various in vitro methods

SIGNIFICANCE: Contact lens wettability is potentially correlated with friction, which is linked to lens comfort. However, measuring wettability can be highly variable. This study assessed wettability using three techniques for a more accurate profile. PURPOSE: To evaluate the wettability of contemporary daily disposable contact lenses after 16 hours on an in vitro model using the sessile drop, captive bubble, and a novel in vit ro noninvasive …
