Overall Satisfaction With the Lenses
Time Frame: 1 week of wear
|
Overall satisfaction with the lenses was interpreted by and assessed by the subject as a single, retrospective measurement of one week's wear time.
Overall satisfaction with the lenses was recorded on a questionnaire as a numerical rating on a scale of 1 to 100, with 1 being completely dissatisfied, and 100 being excellent, completely satisfied.
