Brief Summary

The primary objective of this study is to evaluate the overall performance of PRECISION1 contact lenses when compared to Clariti 1-Day contact lenses.

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.

Primary Outcome Measures
NameTimeMethod
Distance Visual Acuity (VA) With Study LensesDay 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.
