Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Binocular visual acuity at distance (4 meters) at Week 1	Visual Acuity (VA) will be assessed at a distance of 4 meters for both eyes together under high contrast, high illumination lighting with study lenses in place. VA will be measured using letter charts and recorded in logarithm minimum angle of resolution (logMAR), with a logMAR value of 0 equating to 20/20 Snellen VA (normal distance eyesight) and lower logMAR values representing better eyesight.	Week 1 (Day 7 -0/+1 days) of each wear period. A wear period is 14 days (-0/+2 days) according to randomization assignment.
