5. Study Description
Brief Summary
The purpose of this study is to evaluate the clinical performance and subject's preference out of three LRE (Limbal Ring Enhancing) lens types: etafilcon A (Johnson&Johnson), methafilcon A (Interozzo), and methafilcon A (CooperVision).
Detailed Description
This will be a subject-masked, bilateral, randomized, crossover dispensing study to compare clinical performance and subjective preference out of three lens types. Sixty subjects will be assigned into three groups and each group will wear the test and control lenses as matched pairs for one week in random order. Lenses will be worn on a daily wear, daily disposable schedule.
