Conditions studied: Dry Eye Disease

In brief

The purpose of this study is to investigate how the addition of a new artificial tear product when applied to the tear layer affects contrast sensitivity and optical aberrations over time. We will also determine if there are any adverse effects associated with drop instillation.
