Study Overview
Brief Summary
The purpose of this study is to investigate the overall clinical performance of the somofilcon A daily disposable test soft contact lens compared to the somofilcon A daily disposable control soft contact lens.
Detailed Description
The purpose of this study is to evaluate the clinical performance of an investigational silicone-hydrogel contact lens (test) against a marketed silicone-hydrogel contact lens (control) when worn on a daily disposable wear modality over 1 week (for each lens) in a randomized, bilateral, cross-over, dispensing study.
