Daily disposable contact lenses
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. |

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.
