Primary Outcome Measures
NameTimeMethod
Mean Distance Visual Acuity (logMAR) With Study LensesDay 1, Day 30 after 6-8 hours of wear, each product

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). On Day 30, VA was assessed after 6-8 hours of wear. 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.
