Primary Outcome Measures

Name	Time	Method
Least Squares Mean Distance VA (logMAR) With Study Lenses	Day 8, each study lens type	Distance visual acuity (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.
