Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Distance Visual Acuity (VA) With Study Lenses	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.	Day 8 (-0/+3 days) after 10 (-2/+6) hours of wear, each study lens type
