Performance Evaluation of Different Daily Disposable Silicone Hydrogel Contact Lenses.

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to compare the performance of two daily disposable silicone hydrogel contact lenses.

Detailed Description
-----------------
This study is a prospective, bilateral eye, double masked, randomized, 1-week crossover, daily wear design involving two different daily disposable lens types. Each lens type will be worn for approximately one week.
