Primary Outcome Measures:
  • Initial Comfort [ Time Frame: Baseline ]
    Initial Comfort will be assessed bilaterally by the participant at time of dispense. Initial Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).


Secondary Outcome Measures:
  • End of Day Comfort [ Time Frame: Day 7 ]
    End of Day Comfort will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. End of Day Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

  • Overall Comfort [ Time Frame: Day 7 ]
    Overall Comfort will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. Overall Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

  • Overall Handling at Time of Removal [ Time Frame: Day 7 ]
    Overall Handling at Time of Removal will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. Overall Handling at Time of Removal will be graded on a 1-10 scale (10=excellent, very easy; 1=unmanageable).
