Overall Quality of Vision Primary · Day 8, each product

Overall quality of vision was collected binocularly and rated on a 10-point scale with 1 = poor to 10 = excellent. Subjects were asked "Thinking back over the last week, please rate our study lenses. Rate eyes together." No formal hypotheses was conducted; hence no inferential testing was performed.
