Study 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.

Primary Outcome

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.

Interventions
