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:
