About this study

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.

Primary outcomes

  1. Distance Visual Acuity (VA) With Study Lenses

    Time frame: 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.
