This study is a multi-site, group sequential, adaptive, randomized, double-masked, 2×2 crossover design, 1-week dispensing study. Subjects will wear bilaterally both Test and Control lenses in a random order for 1-week each as a daily disposable modality with a wash-out period of 1 week between the wearing periods.

The subject must have best corrected visual acuity of 20/25 or better in each eye. Exclusion Criteria: 1. Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued). 2. Any systemic disease, autoimmune disease, or use of medication that may interfere with contact lens wear. 3. Any previous, or planned, ocular or interocular surgery (e.g., radial keratotomy, PRK, LASIK, etc.). 4. Any ocular infection. 5. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear. 6. Monovision or multi-focal contact lens correction. 7. Participation in any contact lens or lens care product clinical trial within 14 days prior to study enrollment. 8. History of binocular vision abnormality or strabismus. 9. Any infectious disease (e.g., hepatitis, tuberculosis) or a contagious immunosuppressive disease (e.g., HIV, by self-report). 10. Suspicion of or recent history of alcohol or substance abuse. 11.

Primary | Overall Comfort Scores | Subjective assessment of comfort 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. | 1-Week Follow-up | |
