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

The purpose of this study was to evaluate visual acuity at distance when wearing DDT2 contact lenses compared to Clariti contact lenses.

Study Overview

• Status: Completed

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
