Overview
Brief Summary
The purpose of this study is to compare the clinical performance of PRECISION1 contact lenses with Biotrue contact lenses.
Detailed Description
Subjects will be expected to attend 3 visits. Subjects will be expected to wear their study contact lenses every day for at least 10 hours per day over an 8-day period for each study lens type. The total duration of a subject's participation in the study will be up to 22 days.

Outcomes
Primary Outcomes
Least Squares Mean Distance Visual Acuity (VA) With Study Lenses
Time Frame: Day 8 (-0/+3 days), each study lens type
Visual Acuity (VA) was collected for each eye individually with study lenses in place using a letter chart. VA was measured in logarithm of the minimum angle of resolution (logMAR). A logMAR value of 0 corresponds to 20/20 Snellen acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity.
