Primary Outcome Measures
NameTimeMethod
Binocular visual acuity at distance (4 meters) at Week 1Week 1 (Day 7 -0/+1 days) of each wear period. A wear period is 14 days (-0/+2 days) according to randomization assignment.

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.
