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 following 1 night of extended wear.
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 4 scheduled study visits. The lenses will be worn continuously from the time of dispense on Day 1 until lens collection at the Day 2 Follow-up/Exit Visit.

Visual Acuity (VA) With Study Lenses, Collected by Eye
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.
Time frame: Day 1 Dispense; Day 1 Follow-up Prior to Sleeping; Day 2 Follow-up Upon Eye Opening; Day 2 Follow-up Approximately 1 Hour after Awakening/Exit
