Primary Outcome Measures

Name	Time	Method
Distance Visual Acuity (VA) With Study Lenses	Day 8 (-0/+3 days) after 10 (-2/+6) hours of wear, each study lens type	Distance VA was assessed with study lenses in place. VA was collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal visual acuity), with a negative value denoting better than 20/20 visual acuity. No formal hypothesis was predefined for the primary endpoint. No inferential testing was performed.
