- Brief Summary
This study is a multi-site, group sequential, adaptive, randomized, double-masked, 2×2 crossover design, 1-week dispensing study.

- Primary Outcome Measures
Name Time Method Overall Vision Score 1-Week Follow-up Subjective assessment of vision will be performed using the Contact Lens User ExperienceTM (CLUE) questionnaire. CLUE is a validated patient reported outcomes (PRO) questionnaire used to assess patient experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a US contact-lens wearing population between 18 and 65 years of age. CLUE composite scores are derived using Item Response Theory (IRT) and follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response. A 5-point increase in an average CLUE score translates into 10% shift in the distribution of scores for the population of soft disposable contact lens wearers.
