About this study

The purpose of this study is to evaluate the extent to which symptoms improve in symptomatic contact lens wearers when fit with one of two different daily disposable contact lenses.

What is being measured

The primary outcome is the main question the study is designed to answer.

Lens Awareness
Lens awareness, as interpreted by the subject and reported by the subject in a questionnaire as a single, retrospective evaluation of 4-week's wear time. Frequency of lens awareness was measured on a 4-point scale, with 1 being never and 4 being always. Four-week ratings were compared to baseline ratings, and a negative difference (4 week minus baseline) represented an improvement.
Measured: 4 weeks of wear
