Clinical Comparison of DDT2 Contact Lens and a Daily Disposable Contact Lens - Study 2

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to evaluate visual acuity at distance when wearing DDT2 contact lenses compared to Clariti contact lenses.

Detailed Description
-----------------
Subjects were expected to attend 3 study visits and wear the DDT2 and Clariti study lenses in a crossover design for approximately 14 - 20 days (7 - 10 days for each product).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Least Squares Mean Distance Visual Acuity With Study Lenses | Visual acuity was assessed and 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. | Day 8, each product |
