Detailed Description
Subjects are expected to attend 3 study visits and wear the PRECISION1 and Clariti 1-Day study lenses in a crossover design for approximately 8 days of exposure to each study lens type. The expected duration of subject participation is up to 22 days.

Outcome Measures
Primary Outcome Measures
- Distance Visual Acuity (VA) With Study Lenses [Day 8 (-0/+3 days) after 10 (-2/+6) hours of wear, each study lens type]
Distance 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. No formal hypothesis was predefined for the primary endpoint. No inferential testing was performed.
