Refractive Error Clinical Trial
Official title:
Pilot Study on the Effect of Daily Disposable Silicone Hydrogel Contact Lenses on Tear Film Lipids
The purpose of this study is to evaluate the tear film evaporation of symptomatic soft contact lens wearers in the absence of contact lens wear and after at least 8 hours of contact lens wear.
This study consists of 5 visits (1 screening, 4 assessment) with a maximum of 6 days between assessment visits and at least 24 hours of no lens wear the day prior to the visit. Each subject will be randomized to a crossover sequence of 4 periods. Different study lenses will be worn during 3 of the periods, for at least 8 hours each, and the remaining period will have no lens wear. ;
