Overview
Brief Summary
The purpose of this study is to compare the clinical performance of PRECISION1™ contact lenses to Clariti® 1 day contact lenses.
Detailed Description
Subjects will be expected to attend 3 study visits and wear the study lenses daily for at least 10 hours per day. On the day prior to Visits 2 and 3, subjects will be expected to wear the study lenses for at least 16 hours. The total duration of subject participation will be up to 22 days.

Outcomes
Primary Outcomes
Least Squares Mean Distance VA (logMAR) With Study Lenses
Time Frame: Day 8, each study lens type
Distance visual acuity (VA) was assessed with study lenses in place. VA was collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal visual acuity), with a negative value denoting better than 20/20 visual acuity.
