Primary Outcome Measures:
- Overall Comfort [ Time Frame: 3 months of wear, replacing lenses monthly ]As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 3 months of wear time. Overall comfort was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.
Secondary Outcome Measures:
- Overall Lens Fit [ Time Frame: 3 months of wear, replacing lenses monthly ]As assessed by the investigator at study visit using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye. Lens fit was graded by eye on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight
