Mean Distance Visual Acuity (VA) With Study Lenses
Time Frame: Week 1, each product
|
VA was assessed at a distance of 4 meters using a letter chart and 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.
