Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Distance VA (logMAR) With Study Lenses	Visual acuity (VA) was collected for each eye individually with study lenses in place at a distance of 4 meters using a letter chart. VA was measured in 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.	Day 30 after a minimum of 6 hours of wear, each product
