Study Summary
The purpose of this study is to assess the clinical performance of an investigational contact lens over 30 days of daily wear.
Primary Outcome
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.
