Type	Measure	Description	Time frame	Safety issue
Primary	Least Squares Mean Distance VA (logMAR) With Study Lenses	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.	Day 8, each study lens type
