The purpose of this clinical study is to evaluate the on-eye performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn continuously for up to 1 week.
Subjects will be randomized to wear the investigational contact lens in 1 eye and the commercially available contact lens in the other eye. Subjects will be expected to attend 3 scheduled study visits: Day 1 Screening/Baseline/Dispense; Day 2 Follow-up within 4 hours of awakening (after the first night of sleeping); and Week 1 Follow-up/Exit. The expected duration of exposure to each of the study lenses for all randomized, completed subjects was approximately 7 days / 6 nights of wear.

| Distance Visual Acuity (VA) With Study Lenses | Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity. No formal hypothesis testing was planned. | Day 1 Dispense; Day 2 Follow-up (within 4 hours of awakening); Week 1 Follow-up/Exit |

Adverse events (AE's) were collected from time of consent to study exit, approximately 7 days.
AE's were obtained through solicited and spontaneous comments from subjects and through observations by the Investigator. "At Risk" population for ocular AEs is reported in units of eyes; all other populations are reported in units of participants. The safety analysis set includes all eyes exposed to a study lens evaluated in this study.
